Betty runs a day care center. Of the 18 children at the day care center, 4 of them are seven-year-olds.
What is the probability that a randomly selected child will be a seven-year-old?
Write your answer as a fraction or whole number.
P(seven-year-old)=
4 out of 18 children are seven-year-olds, so the probability of randomly selecting a seven-year-old child is:
P(seven-year-old) = 4/18 = 2/9
Therefore, the probability is 2/9.
