Find the area to the left of 2 on a standard normal distribution

In statistics the standard normal distribution is a probability distribution with a mean of 0 and a standard deviation of 1. Area is used to determine probabilities. The area we need can be found by integrating or by using what is called a "z-table". We seek the value 
%0D%0AP%28x%3C2%29=0.9772%0D%0A
