Question

A die is rolled twice. What is the probability of showing a 5 on the first roll and an even number on the second roll?

Answer 1

Answer and Explanation:
The number of elements of the sample space is, n(S)=36 n ( S ) = 36 . Let A be the event of getting a 5 on the first roll and an even number on the second roll. So the number of elements of A is, n(A)=3 n ( A ) = 3 .

Answer 2

1/6 for the first roll

1/2 for the second

Explanation:

5 is one out of 6 faces on a die

so, 1/6

There are 3 even numbered sides out of six

so 3/6 or 1/2
