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}, |
and answer the following.(a)Find
