Suppose there are 25 different types of coupons and suppose that each time one obtains a coupon, it is equally likely to be any of the 25 types. Compute the expected number of different types that are contained in a set of 10 coupons.

4. Suppose you continually collect coupons and that there are two different types of coupon, type A and type B. Suppose also that each time a new coupon is obtained it is a type A coupon with probability 1/3 and a type B coupon with probability 2/3, independently of what coupons you have collected so far. Let X be the number of coupons collected until you have at least one coupon of both types. (a) Find the probability mass function...

Suppose there are n type of coupons. Each new coupon collected is of type i with probability Pi, independently of any other collected coupon. Here, D=1 Pi = 1. Suppose k coupons are collected. Let A be the event that there is at least one coupon of type i among the k collected. For i #j, (1) Compute P(A|AU A;) (2) Compute P(A|Aj)

1. Suppose there are m 2 1 different types of coupons, and a total of n coupons is to be collected. Each new coupon collected is, independent of the past, a type i coupon with probability i, 1 < i< m. Define for i-1,... ,m, Х,-{ 0, otherwise 1, if at least one type i coupon is among the n collected, type Let X = Xut + x,n. Calculate E(X) and Var(X).

Problem 1. Stanislaw is collecting coupons. Each day he receives randomly one of n distinct coupons with equal probabilities (independently of other days (a) Let T be the number of days it takes Stanislaw to obtain a complete set. Explain why T can be written as a sum of n independent Geometric random variables and say what their parameters are (b) Compute the expected value of T. (Use the fact that the expectation of a sum of random variables is...

Q. Given 25 different type of coupons, one coupon is obtained each time. one set obtain 10 coupon. The probability that the type i coupon is not in the set is 24C10/25C10. Is it right? (24C10 => combination) If wrong, please tell me the answer. (i is range 1~25. coupon type index)

The coupon collector problem calculates the expected number of days it takes to get n different coupons, if one receives one of the n coupons at random each day. The number of days is approximately n(0.577 + ln n). Use this to calculate the expected number of TCP connections a random port scan (scanning port numbers 0 through 1023) needs to eventually check all 1,024 well- known port numbers.
Exercise 12.6 At each stage, one can either pay 1 and receive a coupon that is equally likely to be any of n types, or one can stop and receive a final reward of jr if one's current collection of...
Exercise 12.6 At each stage, one can either pay 1 and receive a coupon that is equally likely to be any of n types, or one can stop and receive a final reward of jr if one's current collection of coupons contains exactly j distinct types. Thus, for instance, if one stops after having previously obtained six coupons whose successive types were 2, 4, 2, 5, 4, 3, then one would have earned a net return of 4r -6. The...

(12 points) A software function generates a random number N digits long. Each digit is determined by randomly selecting a value from 0 through 9. All ten values are equally likely, and different digits may have the same value. Determine the minimum length N such that there is at least a 50% probability that at least one digit will have the value 0.
