Standard Deviation Question

A company produces boxes of candy that contain a mean of 50 candies each. The standard deviation is 2.

What percentage of the boxes will quality control reject as containing too few candies?


So this is a 2 part question; I already completed part A which was asking for the probability that a box selected at random contains exactly 51 pieces, but I'm dumbfounded on part B, any ideas?
 
Anything known about the probability distribution of the number of candles? Just knowing the mean and the standard deviation might not be enough to answer the question.
