Explanation:
Detailed explanation-1: -We can see that, there are 10 perfect squares from 1 to 10. But, there are only 8 square roots between 1 to 10 after excluding 1 and 10. Therefore, the number of perfect squares between 1 to 100 natural numbers is 9.
Detailed explanation-2: -How many Perfect Squares are between 1 and 100? There are eight perfect squares between 1 and 100 (i.e., excluding 1 and 100). They are 4, 9, 16, 25, 36, 49, 64 and 81.
Detailed explanation-3: -100. So the odds of randomly picking a number from 1 to 100, inclusive, and it being a perfect square (the square of an integer) is exactly 10/100, or 1/10, or 10%.
Detailed explanation-4: -Hence, the probability that it is a perfect square is 507. Was this answer helpful?
