Question 623717: Of 78 people who answered "yes" to a question, 20 were male. Of the 72 people who answered "no" to the question, 19 were male.
If one person is selected at random from the group, what is the probability that the person either answered "yes" or was male?
78 answered "yes" plus 19 males who answered "no", so 78 + 19 = 97 people either answered "yes" or were male. Divide 97 by the total number of people who answered the question. Hint: Assume that nobody answered "maybe" or anything but "yes" or "no" (because unless you make this assumption, you cannot answer the question.
