Question

In a hospital ward, there are 10 nurses and 6 doctors. 4 of the nurses and 3 of the doctors are male. If a person is randomly selected from this group, what is the probability that the person is female or a doctor?

Answer 1

So 10 nurses + 6 doctors = 16 right?

Answer 2

4 nurses are male, and 3 doctors are male. That's 7 males.

Anyway, here is what we know now. 7 are male, 9 are female, and 6 are doctors.

Answer 8

Since 3 of the doctors are female, we don't want to double count them. Let's just say there are 9 female and 3 doctors. Since it's asking if its a female OR a doctor.

Answer 10

So that would give us 12/16 is the answer.

Answer 11

We can simplify 12/16 to 3/4. So if it ask you to simplify the answer, 3/4 is the correct answer. If not, the answer is 12/16.

Answer 12

Formula for this is P(female or doctor) = P(female) + P(doctor) - P(female and doctor)
