Question

You roll a fair 6-sided die.
What is P(roll an even number)?

Answer 1

Answer:
`(3)/(6)` or 0.5

Explanation:

It has 6 sides, {1,2,3,4,5}. So the total number of cases is 6.

Even number includes {2,4,6}. The sample space of rolling an even is 3.

The probability of rolling an even number formula is:

P(Rollinganevennumber)=
`(Number of cases in the sample space​)/(Total number of cases)`

The probability of an even number is
`(3)/(6)` or 0.5
