the area of all bars = 1 when measuring probability.
Area is 1, because area is always 1 when measuring probability
length is 10
if length is 10 ( 20 - 10 ) and area is 1 ( it has to be beacuse its probability ) whats height? area = l*h
1 = 10 * x 1 = 10 * .1 height has to be .1
Uniform Distribution
12 - 12.50 is a range of .5
width is .5 and height is .1 so multiply together and get .05
