g An immunologist is studying blood disorders exhibited by people with rare blood types. It is estimated that 10% of the population has the type of blood being investigated. Volunteers whose blood type is unknown are tested one at a time. The immunologist needs 5 people to complete her study. What is the probability that she will find the fifth person for her study when she tests her tenth volunteer

Probability of fifth person = p (5/10)

                                               = p (1/2)

Explanation has given below.

Step-by-step explanation:

The population has the type of blood  investigated = 10%

The immunologist needs five people to complete her study.

Probability of finding a 5th person when she starts tests her 10th volunteer?

Probability = p ( 10C5)

                   = 252%

                  =2.52

When she tested her 10th volunteer,

There is a 2% probability that she will find a fifth person for her study.

Another way to find out the probability of the fifth person,

When she started her 10th volunteer.

Probability of fifth person = p (5/10)

                                               = p (1/2)

the correct answer is a.) bc< mn 5 stars if this you : )
