Hint: to solve this question we will find all the possible outcomes we can get on throwing the die. And for event A we will see from all outcomes, which numbers are perfect squares and then we will denote the Sample space and event A in set notation.

Now, there is an event A which is defined as the number is a perfect square. In sample space { 1, 2, 3, 4, 5, 6 }, there are only two perfect squares which are 1 and 4 as ${{\text{1}}^{\text{2}}}\text{=1, }{{\text{2}}^{\text{2}}}\text{=4}$.
