    Answer:

    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
