<span>Given are the following data:
Heart failure causes:
84% natural occurence
16% outside factors
18 individuals (sample size)
1. What is the probability that 3 individuals have conditions caused by outside factors?
Probability = 3/18 * 0.16 = 0.0267 or 2.67%

I prefer to use compatible numbers because by using this method it is easier to make a sum mentally. This is true because compatible numbers are close in value to the actual numbers. For a better understanding, let's take an example:
Suppose you have two numbers, namely 640 and 40. These two numbers are compatible for division because:
64 ÷ 4 = 16
So, we have used mental arithmetic to solve a more complex problem.
