Step 1

Step 2

The total number of persons, including persons who are smokers and non-smokers, and who have low, normal or high blood pressures is 284 (= 80 + 42 + 30 + 22 + 75 + 35).

Out of these, total number of smokers is 185 (= 80 + 30 + 75).

Thus, the probability of choosing a smoker is:

P (x) = (Number of smokers) / (Total number of persons)

= 185/284

≈ 0.6514.

Thus, the probability of choosing a smoker is 0.6514.
