REVIEW OF DISCRETE DISTRIBUTIONS EXERCISE 1: For each, state the type of distribution, THEN create the probability distribution and determine the expected value. a) A card is selected from a deck. The number or letter on the card is recorded, the card is returned to the deck and the deck is shuffled. This process is repeated 10 times and X represents the number of aces selected. b) A single card is selected from a deck. X represents the number on the selected card (ace = 1, jack = 11, etc.) c) Ten cards are selected from a deck without replacement. X represents the number of aces EXERCISE 2: 1. A box of 12 tins of tuna contains three which have gone bad. Suppose 7 tins are opened for inspection. What is the probability that: a) None of the seven have gone bad b) The inspector finds two or three tins which have gone bad 2. The flash mechanism on a camera fails on 10% of shots. A photographer takes 10 indoor shots with this camera, using the flash. What is the probability that: a) the flash mechanism fails exactly twice? b) the flash mechanism fails more than half of the time (you may

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.
