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 1,129

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

P(regular drinker or heavy drinker) = P(regular drinker) + P(heavy drinker)
= (159/1129) + (71/1129)
= 230/1129
= .204
