Question

June rolls a fair dice 132 times. How many times would June expect to roll an even number?

Answer 1

66

Explanation:

A typical dice has 6 sides, 3 (50%) even and 3 (50%) odd. Therefore 50% of rolls should theoretically result in an even number. 50% of 132 is the same as
`(1)/(2)`*132, which can be written as
`(132)/(2)`. This can be evaluated to 66. This is not necessarily the amount of times it will occur (as there are discrepancies), but it is the approximate amount expected of a dice with an even amount of sides.
