A computer retail store has 15 personal computers in stock. A buyer wants to purchase 3 of them. Unknown to either the retail store or the buyer, 3 of the computers in stock have defective hard drives. Assume that the computers are selected at random.
(a) In how many different ways can the 4 computers be chosen?
(b) What is the probability that exactly one of the computers will be defective?
(c) What is the probability that at least one of the computers selected is defective?
Answer:
a. 1365 ways
b. Probability = 0.4096
c. Probability = 0.5904
Explanation:
Given
PCs = 15
Purchase = 3
Solving (a): Ways to select 4 computers out of 15, we make use of Combination formula as follows;
[tex]^nC_r = \frac{n!}{(n-r)!r!}[/tex]
Where [tex]n = 15\ and\ r = 4[/tex]
[tex]^{15}C_4 = \frac{15!}{(15-4)!4!}[/tex]
[tex]^{15}C_4 = \frac{15!}{11!4!}[/tex]
[tex]^{15}C_4 = \frac{15 * 14 * 13 * 12 * 11!}{11! * 4 * 3 * 2 * 1}[/tex]
[tex]^{15}C_4 = \frac{15 * 14 * 13 * 12}{4 * 3 * 2 * 1}[/tex]
[tex]^{15}C_4 = \frac{32760}{24}[/tex]
[tex]^{15}C_4 = 1365[/tex]
Hence, there are 1365 ways
Solving (b): The probability that exactly 1 will be defective (from the selected 4)
First, we calculate the probability of a PC being defective (p) and probability of a PC not being defective (q)
From the given parameters; 3 out of 15 is detective;
So;
[tex]p = 3/15[/tex]
[tex]p = 0.2[/tex]
[tex]q = 1 - p[/tex]
[tex]q = 1 - 0.2[/tex]
[tex]q = 0.8[/tex]
Solving further using binomial;
[tex](p + q)^n = p^n + ^nC_1p^{n-1}q + ^nC_2p^{n-2}q^2 + .....+q^n[/tex]
Where n = 4
For the probability that exactly 1 out of 4 will be defective, we make use of
[tex]Probability = ^nC_3pq^3[/tex]
Substitute 4 for n, 0.2 for p and 0.8 for q
[tex]Probability = ^4C_3 * 0.2 * 0.8^3[/tex]
[tex]Probability = \frac{4!}{3!1!} * 0.2 * 0.8^3[/tex]
[tex]Probability = 4 * 0.2 * 0.8^3[/tex]
[tex]Probability = 0.4096[/tex]
Solving (c): Probability that at least one is defective;
In probability, opposite probability sums to 1;
Hence;
Probability that at least one is defective + Probability that at none is defective = 1
Probability that none is defective is calculated as thus;
[tex]Probability = q^n[/tex]
Substitute 4 for n and 0.8 for q
[tex]Probability = 0.8^4[/tex]
[tex]Probability = 0.4096[/tex]
Substitute 0.4096 for Probability that at none is defective
Probability that at least one is defective + 0.4096= 1
Collect Like Terms
Probability = 1 - 0.4096
Probability = 0.5904

Once you have a listing of every unique combination of salesperson, product and location, what Excel function would you use to compute the total sales for each combination of salesperson, product and location
Answer:
SUMIFS
Explanation:
As we know that the excel is used to present the data in a very attractive way by applying the formulas, pie charts, functions as a pivot table, goal seeking, macros, etc
In order to determine the total sales for each and every sales person, production and location combination we use the SUMIFS function so that the total of each column could come in an easiest and better way

A switch operates in the OSI reference model __________ layer and uses the __________ address to forward packets.
Answer:
A switch operates in the OSI reference model data link layer and uses the MAC address to forward packets
Explanation:
A network switch used in wired physical network connection, has several ports and acts as the bridge in the network of computing devices with a port naming system based on MAC addresses to forward data receives at the OSI model data link layer. By incorporating the capability of routing, switches can forward data at the network layer, known as layer 3.

If you were doing a regular expression inside a Linux command line, which special character on the keyboard would give you two possible matches using the example below: car ____ truck
Answer: car | truck
Explanation: The pipe (|) symbol used can be used in regular expression to simply imply OR. This means when used in between expression, can be used to search for all matches of the strings in which it stands in between. In the scenario above, If the pipe symbol is located in between the two strings, such as [ cars | trucks], the expression returns possible occurrence of the strings cars and trucks. It may also be used to locate and return the occurrences of more than 2 strings, such as; string1 | string2 | string3

What will the computer print if the input for year_variable is 1700?
if year_variable == 1776:
print("Your answer is correct. The Declaration of Independence was signed in “year_variable”.")
elif year_variable 1776: compute_variable = year_variable - 1776
print("Subtract “compute_variable” years from your answer for the correct answer.")
Your answer is incorrect. The Declaration of Independence was signed in 1776.
Subtract 76 years from your answer for the correct answer.
Add compute_variable years to your answer for the correct answer.
Add 76 years to your answer for the correct answer.
PLEASE EXPLAIN HOW YOU GOT IT
Answer:
D. Add 76 years to your answer for the correct answer.
Explanation:
Write the code in python and make year_variable= 1700
Since the input value is 1700, it is less than 1776. This means the elif year_variable < 1776:
would run. This line of code makes whatever the input value is to be subtracted from 1776, then produce an answer labeled as "compute_variable"
This "compute_variable" is then shown to be in a print function, where it says to add whatever the compute variable is to the input, to get the correct answer.
Answer:
The answer is D.
Explanation:
Hope it helps! =D got it on edge
Memory operations currently take 30% of execution time of program A. A new widget called a "cache" speeds up 80% of memory operations by a factor of 4. A second new widget called a "L2 cache" speeds up half of the remaining 20% by a factor of 2. What is the total speed up?
Answer:
The answer is "1.24"
Explanation:
Formula:
[tex]\bold {Speedup= \frac{1}{(1 - non-speedup-portion) +(Speed up portion 1)}+\frac{(speed up-portion \ 2)}{ speedup\ 2}+ ....}\\\\[/tex]Given value:
Operations in the memory = 30%
= 0.3
80% Memory [tex]= 0.3 \times 80\%[/tex]
[tex]=[/tex] [tex]\frac{(0.3 \times 80) }{100}[/tex]
[tex]= 0.24[/tex]
Now it takes 0.06 seconds, saved 0.18 seconds.
20% of the memory operations:
[tex]= 0.3 \times 20\% \\\\= \frac{(0.3 \times 20)}{100} \\\\= 0.06[/tex]
Half of the other 20% = 0.03
It takes 0.015 seconds now, saved 0.015 seconds, saved 0.195 seconds.
It takes 0.805 seconds in the 1 second.
[tex]Speedup = \frac{1} {0.7 + 0.3\times \frac{0.8}{4}} + 0.3\times0.2\times\frac{0.5}{2} + 0.3\times0.2\times0.5[/tex]
[tex]Speedup = 1.2422[/tex]
