Michelle has a fair number cube. Each face has a different number from 1 through 6. She will roll the number cube twice. What is the probability that she will roll an even number on the first roll and a 5 on the second roll?

Answer :

Answer:

Probability is 1/12.

Explanation:

So the chance that she will roll an even number on her first roll is 3 out of 6, or simplified 1 out of 2. On her second roll, the probability that she will roll a 5 is 1 out of 6. To roll these both as a pair consecutively, you would need to multiply their probabilities. You do [tex]\frac{1}{2}[/tex] x [tex]\frac{1}{6}[/tex]  which is equal to [tex]\frac{1}{12}[/tex] .
