Question

An integer is chosen at random from the first 50 positive integers. what is the probability that the chosen integer is divisible by 5?(Ans=1/5)

Answer 1

The probability that the chosen integer is divisible by 5 is 1/5.

Step-by-step explanation:

The first 50 positive integers are given by

S = {1, 2, 3, ..., 49, 50}

∴ total number of event points, n(S) = 50

Let A be the event - 'an integer chosen at random from the first 50 positive integers is divisible by 5'.

Then the favourable outcomes are

A = {5, 10, 15, 20, 25, 30, 35, 40, 45, 50}

∴ the number of favourable outcomes, n(A) = 10

Using the classical definition of probability, we can write

P(A) = the probability of getting an integer divisible by 5

= n(A) / n(S)

= 10/50 = 1/5
