## What is the probability of getting perfect squares on both of the dice?

Probability of product of a perfect square when 2 dice are thrown together, is 1) 2/9 2) 1/9 3) 5/18 4) None of these. When two dice are thrown, the number of sample spaces obtained is 36. Therefore, required probability = 8/36 = **2/9**.

## Is 2 a perfect square?
