Question: Given that the Battery Park Battery Company makes, you guessed it, batteries with a yield of 42%. This means that 42% are good and the rest are defective. (Sounds like the company is defective)

a. If one battery is selected, find the probability that it is defective.

b. If two batteries are randomly selected, find the probability that they are both good.

c. If three batteries are randomly selected, find the probability that at least one is good.
