Question

Gavin rolls a fair dice 48 times.
How many times would Gavin expect to roll an even number?

Answer 1

Answer: The number of times Gavin expect to roll an even number =24

Explanation:

Given: Numbers of a fair dice = 1, 2, 3, 4, 5, 6

even numbers = 2, 4, 6

odd numbers = 1, 3, 5

Probability of getting an even number =
`(3)/(6)=\frac12`

If Gavin rolls a fair dice 48 times.

Then, the number of times Gavin expect to roll an even number =
`48*\frac12=24`

Hence, the number of times Gavin expect to roll an even number =24
