Question:
The table below shows the drinking habits of adult men and women.

Men Women Total
Non-Drinker 387 421 808
Occasional Drinker 45 46 91
Regular Drinker 90 69 159
Heavy Drinker 37 34 71
Total 559 570 1129


If one of the 1,129 people is randomly chosen, what is the probability that the person is a man or a heavy drinker? Round your answer to 3 decimal places.

My answer:
P(man or a heavy drinker) = P(man) + P(heavy drinker)
= (559/1129) + (37/1129)
= 596/1129
= .528

    Do you want to include those that are both heavy drinkers and men in your either-or answer?

    (559/1129) + (37/1129) - (90/1129) = ?

    I hope this helps.
