Question

A single six-sided die is rolled twice. What is the probability of rolling an odd number on the first roll and an even number on the second roll?

A. 1/6

B. 1/36

C. 1/4 1/4

D. 1/12 1/12

Answer 1

C.
`(1)/(4)`

Explanation:

Step 1: find the probability to satisfy the first roll

There are 3 odd numbers on the dice, so there's a 3/6 or 1/2 chance of rolling an odd number on the first roll.

Step 2: find the probability to satisfy the second roll

There are 3 even numbers on the dice, so there's a 3/6 or 1/2 chance of rolling an even number on the second roll.

Step 3: multiply the probabilities to get a compound inequality

`(1)/(2) *(1)/(2) =(1)/(4)`

So... choice C? I suppose?
