Unitary Method
The word “unitary” comes from the word “unit”, which means a single and complete entity. In this method, we find the value of a unit product from the given number of products, and then we solve for the other number of products.

Units and Measurements
Measurements and comparisons are the foundation of science and engineering. We, therefore, need rules that tell us how things are measured and compared. For these measurements and comparisons, we perform certain experiments, and we will need the experiments to set up the devices.

Given:
a)
The probability that he/she has prominent wrinkles given that the individual is a heavy smoker is obtained as below:
Thus, the probability that he/she has prominent wrinkles given that the individual is a heavy smoker is 0.6333.
