1.	A page is opened at random from a book containing 100 pages. Find the probability that the page number is a perfect square.
Answer» Number of pages in given book = 100 The page numbers that will be perfectly a square number (If randomly that are selected) are 1,4,9, 16, 25, 36, 49, 64, 81 and 100. ∴ Number of favourable outcomes = 100 Number of all possible outcomes = its number of pages = 100 ∴ Probability of getting a perfect number = 10/100 = 0.1

A page is opened at random from a book containing 100 pages. Find the probability that the page number is a perfect square.

Answer»

Number of pages in given book = 100

The page numbers that will be perfectly a square number (If randomly that are selected) are 1,4,9, 16, 25, 36, 49, 64, 81 and 100.

∴ Number of favourable outcomes = 100

Number of all possible outcomes = its number of pages = 100

∴ Probability of getting a perfect number = 10/100 = 0.1
