A random variable X has mean 3.6. If you make a large number of repeated independent observations of the random variable X, the average value of those observations will be approximately .
Housing Units. Refer to Exercise 5.19.
(a) Which, if any, of the events in parts (a)-(c) are certain? impossible?
(b). Determine the probability of each event identified in part (a).
An ordinary deck of playing cards has 52 cards. Three are four suits_ spade heart , diamond and club with 13 card in each suit. Spade and clubs are black heart and diamond are red. One of these cards is selected at random. Let R denote the event that a red is chosen . Find the probability that a red card is chosen, and express your answer in probability that a red card is chosen and express your answer in probability natation
A and B are events such that . Find.
In each of Exercises 5.167-5.172, we have provided the number of trials and success probability for Bernoulli trials. Let X denote the total number of successes. Determine the required probabilities by using
(a) the binomial probability formula, Formula 5.4 on page 236. Round your probability answers to three decimal places.
(b) Table VII in Appendix A. Compare your answer here to that in part (a).
