Question

According to a certain country’s department of education, 40.0% of 3-year-olds are enrolled in day care.

What is the probability that a randomly selected 3-year-old is enrolled in day care?

Answer 1

Given parameters:

Percentage of enrollment of 3-year-olds = 40%

Unknown:

Probability that a randomly selected 3-year-old is enrolled in a day care = ?

Probability is the likelihood of an event to occur.

Probability =
`(Possible outcome)/(Total out come)`

In this problem, 40% of the total number of 3-year-olds are enrolled in a day care.

We can say, out of every 100 3-year-olds, 40 of them will enroll in day care.

The possible enrollment is 40 and the total is 100;

Input the parameters and solve;

Probability =
`(40)/(100)` =
`(2)/(5)`

The probability that any randomly selected 3 year old is enrolled in day care is
`(2)/(5)`
