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

Step-by-step 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 = $\dfrac{3}{6}=\dfrac12$

If Gavin rolls a fair dice 48 times.

Then, the number of times Gavin expect to roll an even number = $48\times\dfrac12=24$

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