Chapter 4, Problem 18

(choose chapter or problem)

The area covered by $1 \mathrm{~L}$ of a certain stain is normally distributed with mean

$10 \mathrm{~m}^{2}$ and standard deviation $0.2 \mathrm{~m}^{2}$

a. What is the probability that $1 \mathrm{~L}$ of stain will be enough to cover

$10.3 \mathrm{~m}^{2}$?

b. What is the probability that $2 \mathrm{~L}$ of stain will be enough to cover

$19.9 \mathrm{~m}^{2}$?
