Step-by-step explanation:
Total number of people in ward = 16
Number of nurses = 10
Number of male nurses = 4
Number of female nurses = 6
Number of doctors = 6
Number of male doctors = 3
Number of female doctors = 3
We are to find the probability of selecting a female or a doctor.
Probability of selecting a female or a doctor = Probability of selecting a female + probability of selecting a doctor - probability of selecting a female doctor
Probability of selecting a female or a doctor = 9/16 + 6/16 - 3/16 = 3/4
Thus, the probability of selecting a female or a doctor is 3/4
