Nicole, the key phrase here is “given that this person is a man.”
This means that all we are interested in is the row labeled Male.
Married Never Div Widowed Total
Male 69 40 11 3 123
We are asked to find the probability that the person was either Married or Never. So the fraction you want is (69 + 40) / 123. You need to do the arithmetic and reduce it to lowest terms
For part b, just divide the denominator into the numerator, and you get a decimal.
Does this help?
