Rolling a 3: 1 out of 6

Rolling an even number: 3 out of 12

Just remember the sides of your dice.

1 2 3 4 5 6

The question is asking the probability of getting a 3. Well there is ONE 3 out of 6 numbers so 1 out of 6.

1 2 3 4 5 6

Now the second part is asking for an even number. There are THREE even numbers on a dice so it'll be 3 out of 6 but now this is the SECOND ROLL so it'll be 3 out of 12

1 2 3 4 5 6

I put the numbers to explain it a little better in bold, underlined and italicized.
