Let B and C be two events such that P(E)=0.86 and P(C)=0.10. (a) Determine P(B Union C), given that E and C are manually exclusive. (b) Determine P(B Union C),given g and C are independent.

Solution

1) mutually exclusive

so P(B U C) = P(B) + P(C)

2)independant then

P(A ? B) Solution: P(A) + P(B) ? P(A)P(B)
