Cards marked with numbers 5 to 50 are placed in a box and mixed thoroughly. A card is drawn from the box at random. Find the probability that the number on the taken out card is (i) a prime number less than 10 (ii) a number which is a perfect square.

Answer 1

A. Prime no. =
favourable outcome = {5,7} = 2
total number of outcomes = 46
probability = 2/46

total number of outcomes = 46
perfect square =5/46
