36/54 = x/100
54x = 100 * 36
54x = 3600
x = 3600 ÷ 54
x = 66.666666.... so 66.67
First put it into a proportion and then cross multiply. After that you divide both sides by 54 to get x alone which gives you 66.66666 which is rounded to 66.67
Answer: 66.67%

The probability that the participant was a nonsmoker is 25%.
<h3><u>Probability</u> </h3>
Given that at the beginning of a certain study of a group of persons, 15% were classified as heavy smokers, 30% as light smokers, and 55% as nonsmokers, and in the five-year study, it was determined that the death rates of the heavy and light smokers were five and three times that of the nonsmokers, respectively, to calculate, if a randomly selected participant died over the five-year period, the probability that the participant was a nonsmoker, the following calculation must be performed:
- 15 x 5 = 75
- 30 x 3 = 90
- 55 = 55
- 55 + 90 + 75 = 220
- 220 = 100
- 55 = X
- 55 x 100 / 220 = x
- 5500 / 220 = X
- 25 = X
Therefore, the probability that the participant was a nonsmoker is 25%.
