Question

Of the 83 people who answered "yes" to a question, 12 were male. of the 50 people that answered "no" to the question, 5 were male. if one person is selected at random from the group, what is the probability that the person answered "yes" or was male?

Answer 1

First we have to find the amount of people who said yes: 83 (males that said yes are included)
Now lets find the number of males who said no: 5
Now lets get the total people. 83 said yes, 50 said no:

`83 + 50 = 133`
If we add the number of possible outcomes (males or people who said yes)

`83 + 5 = 88`
and put over number of outcomes we got the probability:

`(88)/(133) = 66.17\%`
