1.) Jim pulls a card at random from a normal deck of cards. Find the probability:
(a) Jim draws a red card
(b) Jim gets a 3 or a diamond
(c) Jim draws a red king
2.) A red ball and 4 white balls are placed in a box. If two balls are drawn, without replacement, what is the probability:
(a) of getting a red ball on the first draw and a white ball on the second?
(b) of getting two white balls?
(c) of getting two red balls?
3.) A fashion house sells ascot ties. They have just bought enough fabric to make 6 different ties. However, there is only room enough for 3 ties in the display case. How many different displays are possible if:
(a) The order of the ties represents the asking price? (order matters)
(b) The order of the ties is not important.
4.) Bob and Jody are working on their probability homework and Bob has found that the probability of an event is 2.7. Jody believes he is wrong. Is Jody correct in this assumption, why or why not?
5.) List the four requirements for a binomial distribution. Describe an experiment which is binomial and discuss how the experiment fits each of the four requirements.
6.) The probability that a radish seed will germinate is 0.7. A gardener plants seeds in batches of 12. Find the mean for the random variable X, the number of seeds germinating in each batch.
different games in a casino. What would you expect to be true for all expected values for these seven
games?
7.) A jar contains 10 balls, numbered 0, 2, 2, 3, 3, 4, 4, 4, 5, 5. You are going to draw one ball at random from the jar, and you will be paid the dollar amount that equals twice number on the ball plus one. Let X = the amount that you will be paid. Write the probability distribution of X.
