Probability: Moment Generating Functions and Poisson Process
Let X be a discrete random variable with probability mass function Pr {X=k} = c(1+ k^2) for k= -2, -1, 0, 1, 2.a) Determine c.b) Determine Pr {X <= 0}c) Determine the mean of Xd) Why is the previous answer fairly obvious?e) Determine the variance of Xf) Compute Pr {X=2 | X >= 0}g) Determine the moment generating function of X
Let Y be a Poisson random variable with parameter 1.5a) Compute Pr {Y=0}b) Compute Pr {Y <= 1}c) Compute Pr {Y=0 |Y <= 1}d) What is E[Y]?e) Determine the variance of Yf) Determine the moment generating function
Suppose the random variable S has moment generating function of (q + p *(e^t))^n where q= 1- p, 0 < p < 1 and n is a positive integer. Find the mean and variance of Y.
Analyzing the graph of the given function using first and second derivative
What is the probability that the nut fits the bolt? (Note: the sample space consists of all pairs of nuts and bolts, and each pair is equally likely to be chosen.)
Probability based on normal distribution.
The number of surfer's special burritos served was sampled during a dinner period 5:00 p.m. - 8:30 p.m. at a taco shop on a weekday. Below is the sample:
Which pair has equally likely outcomes? List the letters of the two choices below which have equal probabilities of success, separated by a comma.
Sampling Distribution and Sample Mean : Probability, The shelf life of a digital storage device is normally distributed with mean 10 years and standard deviation 2 years. Suppose you are a quality assurance manager and wish to verify this statisti..

Probability : Combinations, Mr james just won 6 tickets for each of 2 consecutive Giants home football games. For the first game, Mrs James will not be able to attend so he has 5 extra tickets.
T.J.'s market is a small local grocery store with only one checkout counter. Assume that the shoppers arrive at the checkout lane at an average rate of 15 customers per hour and that the average order takes 3 minutes to ring up and bag.
Probability - independence of 2 events. Prove that if A and B are independent events in a probability space, then the events A^c and B^c are also independent.
