Answer:
0.554
Step-by-step explanation:
In the figure attached, the table is shown
Total people: 1156
Nonsmoker men + occasional smoker men + regular smoker men + heavy smoker men + heavy smoker women = men + heavy smoker women = 601 + 39 = 640
Probability that the person is a man or a heavy smoker = 640/1156 = 0.554
(Notice that if you directly add heavy smoker and total men you will count twice heavy smoker men)
