n= 3
p= 0.8
X  Binom(n,p)
P ( X 1 ) = 1 P ( X < 1 )
= 1 P ( X 0 )
= 1 - 0.0080 [Excel command: =BINOMDIST(x,n,p,true) ]
= 0.992

The two-way table summarizes data from an experiment comparing the effectiveness of three different diets (A, B, and C) on weight loss. Researchers randomly assigned 300 volunteer subjects to the three diets. The response variable was whether each subject lost weight over a 1-year period.

Diet Lost weight?ABC Total  Yes 60180 No 40120 Total 90100110300

Suppose we randomly select one of the subjects from the experiment. Show that the events "Diet B" and "Lost weight" are independent.
