Question

The probability of rain is \(80 \%,\) or 0.8 .

Short answer

The probability of rain as a decimal is 0.8.

Step-by-step solution

Understand the problem

In this exercise, the probability of rain is given as 80%. The task is to convert this percentage into a decimal.

Convert the percentage into a decimal

To convert a percentage into a decimal, divide the percentage by 100. The logic here is that 'per cent' means 'per hundred', so to convert to a 'per one' basis (which is what a decimal is), we need to divide by 100. So, \(80\%\) as a decimal is \(80 \div 100 = 0.8\).
