A bag contains 24 discs.
8 are red and 16 are blue.
One disc is taken out at random and replaced by two of the other colour.
Another disc is then taken out at random and replaced by two of the other colour.
Another disk is taken out at random
Work out the probability that all three discs are taken out red
Answer:
Step-by-step explanation:
8/24 are Red
Pick and return 2
So it will be 7/25
Again pick and return 2
Then it is 6/26
Now multiply the results
8/24 × 7/25 × 6/26 = 7/ 325
The probability that all three discs are taken out of red will be 7/ 325.
What is probability?Probability is defined as the ratio of the number of favourable outcomes to the total number of outcomes in other words the probability is the number that shows the happening of the event.
Probability = Number of favourable outcomes / Number of sample
Given that a bag contains 24 discs. 8 are red and 16 are blue. One disc is taken out at random and replaced by two of the other colour. Another disc is then taken out at random and replaced by two of the other colour.
The probability will be calculated as,
Red = 8/24
Pick and return 2 it will be 7/25
Again pick and return 2 then it is 6/26
Now the overall probability will be,
P = 8/24 × 7/25 × 6/26 = 7/ 325
Therefore, the probability that all three discs are taken out of red will be 7/ 325.

arc US = 110°
arc RU =130°
∠RPQ = 60°
arc QRT = 240°
arc UTQ = 290°
Step-by-step explanation:
arc TSR = 180° because half circle
arc US = 110° because 50° + 60°
arc RU =130° because 180° + 50°
∠RPQ = 60° because vertical to 60°
arc QRT = 240° because 180° + 60°
arc UTQ = 290° because 360° - 70°

Answer:
$78.75
Step-by-step explanation:
So we know that After 2 Dogs walked, Irene makes $10.50, so we divide that by 2 (Since he walked 2 dogs) to find out how much walking one dog makes him.
10.50/2=5.25
5.25 x 15= 78.75 (We multiply by 15 because that's how many dogs are needed to find the total money.)

Ben and Landon took turns driving on the recent 820 mile road trip Ben averaged 60 mph while Landon average 56 mph if the trip took them 14 hours how many hours did Landon Drive
Answer:
9 hours
Step-by-step explanation:
Let :
Landon hours = x
Ben hours = y
x + y = 14 - - (1)
60x + 56y = 820 - - - (2)
From (1)
y = 14 - x
60x + 56(14 - x) = 820
60x + 784 - 56x = 820
4x = 820 - 784
4x = 36
x = 36/4
x = 9
Landon drove for 9 hours

There are 16 colored pencils and 8 colored pencils will fit in a box. How many boxes will the 16 pencils fill?
Given:
Total number of colored pencils = 16
Colored pencils fit in a box = 8
To find:
The number of boxed that will fit the 16 pencils.
Solution:
According to the question 8 colored pencils will fit in a box. So, we have
8 pencils = 1 box
Multiply both sides by 2.
2×8 pencils = 2×1 box
16 pencils = 2 box
Therefore, 2 boxes are required to fit the 16 colored pencils.
Isabel baked 2 dozen oatmeal cookies for her family. If two-thirds of the cookies were oatmeal, how many total cookies did Isabel bake?
Answer:
36 total cookies
Step-by-step explanation:
2 dozen = 2/3 of the total cookies
24 = 2/3 of the total cookies
24/x = 2/3
cross multiply
24(3) = 2x
72 = 2x
x = 36
Check the math: 2/3 x 36 = 72/3 = 24
