1/5 or 0.2

Step-by-step explanation:

Probability calculates the likelihood of an event occurring. The likelihood of the event occurring lies between 0 and 1. It is zero if the event does not occur and 1 if the event occurs.

For example, the probability that it would rain on Friday is between o and 1. If it rains, a value of one ids attached to the event. If it doesn’t a value of zero is attached to the event.

Numbers that would be divisible by 5 are multiples of 5

they include = 5, 10, 15, 20, 25, 30, 35, 40, 45, 50, 55, 60, 65, 70, 75, 80, 85, 90, 95, 100

there are 20 numbers

Probability the two numbers would be divisible by 5 = 20/100

To transform to the simplest form. divide both the numerator and the denominator by 20

1/5
