The odd numbers on a regular die are painted red. On a second regular die, the numbers that are one less than a perfect square are painted red. If both dice are thrown, what is the chance that both come up red

If the odd numbers of the first die are painted red, the numbers 1, 3, and 5 are painted red.

On the second die, the only number that is painted red is the number 3.

To get a red numer to be rolled on the first die has a probability of 3/6.

To get a red number to be rolled on the second die has a probability of 1/6.

To get a red number to be rolled on both dice has a probability of (3/6) x (1/6) = 3/36 = 1/12
