Will mark the histogram shows the ages of cars sold at a car auction. what percent of the cars was less than 20 years old or more than 40 years old?

.96% (?)

I know not the correctness of my answer due to:
The Total was 8 to fit the criteria, the others older than 20 but younger than 40 are 12
(However I do not know how to calculate percentage, went to Google and got a percentage calculator to find what percentage 8 is to 12)

40% I hoped me helped

B.the point lies directly on the regression
