Question

Several adults and children were observed to see how many ofthem were wearing glasses. The results are summarized in therelative frequency table. If a person from this group is randomly selected, answer each of the following questions. What is the probability to the nearest hundredth, that a child picked at random does not wear glasses? P(no glasses child)

Answer 1

total number of childs = 0.42

Childs that don't wear glasses = 0.25

P = 0.25 / 0.42 = 0.595 = 0.60

Multiply by 100 to obtain the percentage

0.60 x 100 = 60%
