Question

A Social Studies textbook contains 250
pages. A page is selected at random,
what is the probability that the number
on the page selected is a perfect square?​

Answer 1

Answer:

3/50 will be the probability since 15 numbers are there whose squares comes under 250 and then it is devided by 5 up and down and comes to 3/50

Answer 2

Answer:

7 / 125

Step-by-step explanation:

Let S be the sample space of the page no which are perfect squares.

S = {1, 4, 9, 16, 25, 36, 49, 64, 81, 100, 144, 169, 196, 225}

n(S) = 14

and Total Pages/Elements are 250 => n(A) = 250

Thus probability at the number  on the page selected is a perfect square

= n(S) / n(A)

= 14 / 250

= 7 / 125

Hope you get it

Good Luck!
