Question

A number is selected at random from first 20 natural numbers then probability that the number is multiple of 5

Answer 1

Answer:

The probability that number is divisible by 5 from 1 to 20 is 1/5.

Step-by-step explanation:

Probability is the prediction of getting an outcome.

So total outcomes that we can get is 20. Because there are 20 numbers from 1 to 20.

And favourable outcomes are 5, 10, 15, 20.

So total number of outcomes is 4.

The formula for determining the probability is -

Total number of favourable outcomes/Total number of outcomes.

Which gives- 4/20=1/5.

So the probability is 1/5.
