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?

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  =

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  =   =

The probability that any randomly selected 3 year old is enrolled in day care is

0.16 or 16%

step-by-step explanation:

lets take a coin for example.

if you toss it twice, it has a 1/4 chance of landing on heads both times because 1/2 * 1/2 is 1/4.

with the cards, the chance of picking dog is 0.4. having two people pick one is like picking a card twice in a row. so 0.4 * 0.4 is 0.16, or 16%
