If a standard die is rolled twice, the probability of getting a perfect square is 1/9 and a number that is less than 5 is 1/16.

What is probability?

Probability is a branch of mathematics which tells about the chances of occurring in something.

There are three squares in a standard dice. 1, 2, 4. If there are two dices, then the probability of getting squares are 1/3 x 1/3 = 1/9.

There are four numbers less than 5, so

1/4 x 1/4 = 1/16.

Thus, the probabilities are 1/9 and 1/16.
