Question

Patricia runs a day care center. Of the 15 children at the day care center, 6 of them are seven-year-olds. What is the probability that a randomly selected child will be a seven year old?

Answer 1

The probability that a randomly selected child from the day care center will be seven years old is 0.4, or 40%, calculated by dividing the number of seven-year-olds (6) by the total number of children (15).

Step-by-step explanation:

The question asks about determining the probability that a randomly selected child from a day care center will be seven years old. In the day care center, there are 15 children in total, and out of those, 6 are seven-year-olds. To calculate the probability, we use the formula:

Probability = (Number of favorable outcomes) / (Total number of possible outcomes).

In this case, the favorable outcomes are the seven-year-olds, which we have 6 of, and the total number of possible outcomes is the total number of children, which is 15. So,

Probability = 6 / 15 = 0.4 or 40%.

Therefore, the probability that a randomly selected child from the daycare will be a seven-year-old is 0.4, or 40%.

Answer 2

6/15 = 2/5

Step-by-step explanation:

6 out of 15 = 6/15

simplify the fraction divide both terms by 3 to get 2/5
