Percent of fully-charged cell-phone

Suppose that the life-length of a fully-charged cellphone battery is normally distributed with a mean of 180 minutes with a standard deviation of 20 minutes.

(a) What percent of fully-charged cell-phone batteries have a life-length more than 191 minutes?

(b) 79.95% of fully-charged cell-phone batteries have a life-length more than how many minutes?
