Question

cards marked with numbers 2 to 101 are placed in a box and mixed thoroughly. one card is drawn from this box. find the probability that the number on the card is a) a number less than 14 b) a number which is a perfect square

Answer 1

number of cards = 100

number less than 14 = {2,3,...,13} = 12

number perfect square = {4, 9, 16, 25, 36, 49, 64, 81, 100} = 9

so

a) probability = 12/100 = 3/25

b) probability = 9/100
