Step-by-step explanation:
A dentist has 400 male and female patients that range in age is from 10 years old to 50 years old and up. What is the experimental probability that the next patient will be female and in the age range of 22 through 39?
10-21 22-39 40-50 50+
Male 44 66 32 53
Female 36 50 45 74
There are 400 male and female patient in total
there 400 possible outcome
Total number of possible outcome = 400
There are 50 females in 22-39 range and thus there are 50 favourable outcome
The probability is the number of favourable outcome divided by the number of possible outcome
= 0.125
=12.5%
