Anne is choosing a contractor. She has narrowed down her selection to two companies and will base her decision on the likelihood that the job is done on
time and on budget. She uses online reviews to estimate the probabilities.
Contractor A
Contractor B
Probability that the job
is done on time
0.95
0.98
Probability that the job
is done within budget
0.97
0.93
Which contractor should Anne choose to maximize the probability that the job
will be done on time and on budget? Assume all events are independent.
A. Contractor A. The probability that both conditions are met is 0.92.
B. Contractor B. The probability that both conditions are met is 0.91.
C. Contractor A. The probability that both conditions are met is 0.93.
D. Contractor B. The probability that both conditions are met is 0.90.
