b).what is the probability of it being a perfect square?​

Answer 1

Answer:

170

680

Step-by-step explanation:

1=17+0

170

2.170+170+170+170=

Answer 2

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 .
