2.A certain system can experience three different types of
defects. Let Ai; i = 1, 2, 3 denote the event that the system has a
defect of type i. Suppose that P(A1)= 0.12, P(A1ÈA2)= 0.13, P(A2)=
0.07, P(A1ÈA3)=0.14, P(A3)= 0.05, P(A2ÈA3)=0.10, and P(A1ÇA2ÇA3)=
0.01.
a)What is the probability that the system has both type 1 and
type 2 defects?
b)What is the probability that the system has at least one of
these defects?
c)What is the probability that the system...
