Answer:
The probability that one will end up calling a tow truck because all 10 drivers do not have jumper cables = 0.1749
Step-by-step explanation:
Probability of one driver having jumper cables = 16% = 0.16
Probability that one driver doesn't have jumper cables = 1 - 0.16 = 0.84
The required probability is the probability you end up calling a tow truck.
This probability is equal to the probability that all the 10 drivers asked about jumper cables on the road don't have jumper cables.
Probability that 10 drivers don't all have jumper cables = (0.84)¹⁰ = 0.1749
Hence, the probability that one will end up calling a tow truck because all 10 drivers do not have jumper cables = 0.1749
Hope this Helps!!!
