Answer: A. Contractor A. The probability that both conditions are met is 0.93

Step-by-step explanation:

Probability of two independent events happening can be found by multiplying them.

Probability of A doing the job on time and on budget:

= Probability that job is done on time * Probability it is done on budget

= 0.97 * 0.96

= 0.93

Probability of B doing the job on time and on budget:

= 0.93 * 0.98

= 0.91

Contractor A has the better probability at 0.93 so should be chosen.
