sample space,

7.    If A and B are independent events in a sample space, show that

 

P(A ∪ B) = P(B) + P(A) ⋅ P(B) = P(A) + P(A) ⋅ P(B).

 

8.    In a sample space, events A and B are independent: events B and C are mutually exclusive, and A and C are independent. If P(A ∪ B ∪ C) = 0.9 while P(B) = 0.5 and P(C) = 0.3, find P(A).

9.    If P(A ∪ B) = 0.4 and P(A) = 0.3, find P(B) if

(a)    A and B are independent.

(b)    A and B are mutually exclusive.

10.    A coin, loaded so that the probability it shows heads when tossed is 3∕4, is tossed twice. Let the events A, B, and C, be “first toss is heads,” “second toss is heads,” and “ tosses show the same face,” respectively.

(a)    Are the events A and B independent?

(b)    Are the events A and B ∪ C independent?

(c)    Are the events A, B, and C independent?
