What is the probability of showing a 1 on the first roll and an even number on the second roll?

Question

A die is rolled twice. 

Answer 1

I assume you are talking about dice? Each roll of the dice is an independent event. The probability of a 1 on one roll is 1/6 and the probability of an even number on the second roll is 3/6 = 1/2. Since each roll is an independent event, the probability of a 1 on one roll and an even number on the second roll is 1/6 * 1/2 = 1/12.
