Question
Tokens numbered 1 to 350 are in a bag. What is the
probability that the Token drawn has a number which is a multiple of 6 or 7?Solution
Multiples of 6 up to 350 = 350/6 = 58 (take only whole number before the decimal part) Multiples of 7 up to 350 =350/7 = 50 Multiple of 42 (6×7) up to 350 = 350/42 = 8 So, total such numbers are = 58 + 50 – 8 = 100 Required Probability = 100/350 = 2/7
