Question

32. Event 4 occurs with probability 0.2. Event B occurs with probability 0.8. IfA and B are disjoint (mutually exclusive) then A) P(A and B)= 0.16. B) P(A or B)- 1.0. ,C) P(A and B) = 10. D) P(A or B) 0.16. Use the following to answer question 33: A golf equipment company produces drivers that are stated to be 44 inches long. Suppose that the distribution of the actual lengths of these drivers is normal with mean 44 inches and standard deviation 0.1 inches 33. You purchase a new 44-inch driver from this company. What is the probability that it is longer than 45 inches? A) 0.68 B) 0.32 C) 0.16 D) essentially 0

Explanation / Answer

32) for A and B to be mutually exclusive:

P(A or B)=P(A)+P(B)=0.2+0.8 =1

33)

P(X>45)=P(Z>(45-44)/0.1)=P(Z>10)=0.0000

option D is correct.
