Question

You are stuck at the Vince Lombardi rest stop on the New Jersey Turnpike with a dead battery. To get on the road again, you need to find someone with jumper cables that connect the batteries of two cars together so you can start your car again. Suppose that 16% of drivers in New Jersey carry jumper cables in their trunk. You begin to ask random people getting out of their cars if they have jumper cables. Use Scenario 6-17. You're going to give up and call a tow truck if you don't find jumper cables by the time you've asked 10 people. What's the probability you end up calling a tow truck

Answer 1

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!!!
