The average height for players on a certain basketball team is 73 inches, with a standard deviation of 6 inches. What percent of players' hgeights are:

a.) between 70 and 73 inches?

I did:

1 - 0.8135 = 0.1915 which is 19.15%

So 19.15% of the people are between 70 and 73 inches. But my question is there a faster simpler way of solving this?
