Best ResponseYou've already chosen the best response.2\[P(\text{female or doctor})=P(\text{female})+P(\text{doctor})P(\text{female and doctor})\] There's a total of 11 females (9 nurses, 2 doctors) in the group of 16, and there are 4 doctors. Two of these doctors are also female, so \[P(\text{female or doctor})=\frac{11}{16}+\frac{4}{16}\frac{2}{16}\]
