###### Question details

A master gardener, Pete Moss, has cross-bred a new hybrid flower with bulb germination times that are normally distributed with a mean of 15 days and a standard deviation of 2.4 days.\

What is the probabiltiy that a randomly selected bulb will germinate in over 16 days?

NOTE: I know the steps to the problem but am unsure of how 1-P(Z ≤.42) turns into 1-.6628. Can someone tell me how I figure out the probability turns into .6628? Thanks!
