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 from failing. In a visual picture this will be the space outside of both of the circles. The

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
