Question: Suppose that we have a sample space S = { E 1 , E 2 , E 3 , E 4 , E 5 ,

Suppose that we have a sample space

S= {E1,E2,E3,E4,E5,E6,E7},

where

E1,E2,,E7

denote the sample points. The following probability assignments apply:

P(E1) =0.20,

P(E2) =0.05,

P(E3) =0.15,

P(E4) =0.25,

P(E5) =0.20,

P(E6) =0.05,

and

P(E7) =0.10.

Let

A = {E1,E4,E6}
B = {E2,E4,E7}
C = {E2,E3,E5,E7},
