Question

Sammy counts the number of people in one section of the school auditorium. He counts 18 girls, 24 boys, and 8 adults. There are 650 people in the auditorium. What is the probability that one person selected at random is an adult? 0.84 0.16 0.08 0.01

Answer 1

0.16

Explanation:

24 boys + 18 girls + 8 adults = 50 people

Out of sample of 50 people he counted, 8 were adults. Hence, the percentage of adults is:

`(8)/(50)=0.16` (equal to 16%)

"Assuming the distribution is same for the 650 people in the auditorium, the percentage (or probability) or chosing an adult will be the same"

So, the answer is 0.16
