UNIFORM DISTRIBUTION If every number between 0 and 1 has the same  chance to be picked then the graph of the  distribution looks like a triangle. What is the probability of picking 0.75? Can not find probability of exact values.  Need  to find probability between values: X<value or x>value or                            value- 1<x<value-2
UNIFORM DISTRIBUTION Find the height of the rectangle – p(x). The area of the rectangle is 1 and the base is b  – a, so the height is  Now find the area desired. 1 ( ) p x b a = -

CONTINUOUS PROBABILITY DISTRIBUTIONS AND REMEMBER, IN A CONTINUOUS  DISTRIBUTION: THE AREA UNDER THE CURVE IS THE  % OF THE POPULATION BETWEEN  VALUES OF X; AND THE AREA UNDER THE CURVE  IS THE  PROBABILITY OF SELECTING  A NUMBER BETWEEN THE VALUES  OF X.
