Female is 78
Unemployed is 74
That sum is 152
But we have double counted female and unemployed, so subtract that number, which is at the intersection of the column and the row, or 16.
The number is 136 female or unemployed, the probability is 136/170 or 80%.

            The answer in the post by @Boreal is INCORRECT.

P(is a female OR is employed) = P(is a female) + P(is employed) - P(is a female AND is employed) = = = = 0.66 (rounded), or 66%. ANSWER

Solved.
