Question

An integer is chosen at random from the first 80,000 positive integers. What is the probability
that the integer chosen is divisible by atleast one of the numbers 2,4,6,7?

Answer 1

Answer:

The number of numbers which are divisible by 6 which are less than 200 is 33.

The number of numbers which are divisible by 8 which are less than 200 is 25.

The number of numbers which are divisible by both 6 and 8 which are less than 200 is 8.

Therefore the number of numbers which are divisible by 6 or 8 is 33+25−8=50.

The probability is 50/200 = 1/4.
