Colin rolls a fair dice 18 times.
How many times would Colin expect to roll a number greater than 3?

Answers

Answer:

8 or 1/2

Step-by-step explanation:

The requried probability that colin expects to roll a number greater than 3 is 1/2.

What is probability?

Probability can be defined as the ratio of favorable outcomes to the total number of events.

Here,
Colin rolls a fair die 18 times.
The total outcome of 1 die = 6
So, for 18 die total outcome = 6 × 18

Now,
Favorable outcome = 4, 5, 6 = 3
A total favorable outcome for 18 dice = 3 × 18

Probability, many times would Colin expect to roll a number greater than 3.
= 3 × 18  /  6 × 18
= 1 / 2

Thus, the requried probability that colin expects to roll a number greater than 3 is 1/2.

What is the first step to solve this equation: 3x =44

Answers

You need to divide 3 on both sides

The correct first step to solve the equation 3x = 44 is to divide both sides by 3.

To solve the equation 3x = 44, the first step is to isolate the variable x on one side of the equation.

To achieve this, you need to undo the multiplication by 3 on the left side of the equation.

Since 3x means 3 multiplied by x, you need to divide both sides of the equation by 3.

By dividing both sides of the equation by 3, you are essentially canceling out the effect of the multiplication by 3 on the left side.

This step allows you to isolate the variable x.

So, the correct first step to solve the equation 3x = 44 is to divide both sides by 3.

Hence the correct option is 4th.
