Answer 1

Answer:

1/8

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

$P=\frac{50}{400} \\\\= \frac{1}{8}$

= 0.125

=12.5%
