a. If an airplane has two different alternators with the probability of any one of those alternators to fail is .02, then I will look at what the probabilty of bothe of those to fail is. The events in this situation are independent because one failing does not affect the other one from failing. In a visual picture this will be the space inside the rectangle where the circles overlap. The probability of both of those alternators to fail is .0004. This answer was found using the binomial probability calcualtor where I inputed the sample size which was 2 and enterted the probability of success (or failure in this case). This can also be found by multiplying the two independent event probabilities together, which is . 02*.02=.0004. b. If an airplane has two different alternators with the probability of one of those alternators to fail is .02, then I will look at the probability of neither of the altermators to fail. The events in this situation are independent because one failing does not affect the other one
