The area under the standard normal curve between $z = 1$ and $z = 2$ is found by subtracting the area from $z = 0$ to $z = 1$ from the area from $z = 0$ to $z = 2$. Using standard normal distribution tables or a calculator, the area from $z = 0$ to $z = 1$ is approximately $0.3413$, and the area from $z = 0$ to $z = 2$ is approximately $0.4772$. Subtracting these gives $0.4772 - 0.3413 = 0.1359$.
