Answer:
a.) Probability = 1 / 90.
b.) There are (99–10)+1 positive two digit numbers.
The largest two digit perfect square is 81 (9 squared) and the smallest is 16 (4 squared)
Then the numbers which meet this criteria are:
4,5,6,7,8,9. There are a total of 90 positive two digit numbers, so if we take the probability as the relative frequency, then we get 6/90=1/15 .
