Use the second method of Problem5.11to show that the expected number of successes innBernoulli trials with probabilitypof success isx-=np. Hint: What is the expected number of successes in one trial?

Short Answer

Expert verified

Expected number of successes in one trail, i.e.,x-=np .

Step by step solution

01

Given Information

Assume thatx1 is first experiment, x2is second experiment and so on.

The equation E(x+y)=E(x)+E(y).

A coin is tossed repeatedly; x = number of the toss at which a head first appears.

Let x1,x2,..,xnbe independent random variables, each with density function f(x), expected valueμ , and varianceσ2 . Define the sample meanby.x−=∑i=1nxiShowthatE(x−)=μ,and .var(x−)=σ2n (See Problems 5.9,5.13and6.15.)

Consider the set of all permutations of the numbers 1, 2, 3. If you select a permutationat random, what is the probability that the number 2 is in the middle position?In the first position? Do your answers suggest a simple way of answering the same questions for the set of all permutations of the numbers 1 to 7?

Two decks of cards are “matched,” that is, the order of the cards in the decks is compared by turning the cards over one by one from the two decks simultaneously; a “match” means that the two cards are identical. Show that the probability of at least one match is nearly.1−1/e

(a) Acandy vending machine is out of order. The probability that you get a candybar (with or without return of your money) is12, the probability that you getyour money back (with or without candy) is 12, and the probability that youget both the candy and your money back is 112. What is the probability that youget nothing at all? Suggestion: Sketch a geometric diagram similar to Figure 3.1, indicate regions representing the various possibilities and their probabilities; then set up a four-point sample space and the associated probabilities of the points.

(b) Suppose you try again to get a candy bar as in part (a). Set up the 16-point

sample space corresponding to the possible results of your two attempts tobuy a candy bar, and find the probability that you get two candy bars (andno money back); that you get no candy and lose your money both times; thatyou just get your money back both times.
