The velocity of a particle in a gas is a random variable
X with probability distribution
fX (x) =
32 x2 e−4x ,
x>0. The kinetic energy of the particle is (1/2)
mX 2. Suppose that the mass of the particle is
64 yg. Find the probability distribution of Y. (Do not
convert any units.) Please explain steps. I do not understand how
to solve this kind of question. Thank you! :)

Use Excel to generate the probability distribution for a
binomial random variable for which there are 20 trials (n = 20) and
the probability of success is 0.5 (p = 0.5), and show the
graph.

The demand for a replacement part is a random variable having a
Poisson probability distribution with a mean of 4.7. If there are 6
replacement parts in stock, what is the probability of a stock-out
(i.e., demand exceeding quantity on hand)?

Problem 4) Five coins are flipped. The first four coins will
land on heads with probability 1/4. The fifth coin is a fair coin.
Assume that the results of the flips are independent. Let X be the
total number of heads that result.
(hint: Condition on the last flip).
a) Find P(X=2)
b) Determine E[X]

Assume the random variable X has a binomial distribution with
the given probability of obtaining a success. Find the following
probability, given the number of trials and the probability of
obtaining a success. Round your answer to four decimal places.
P(X=6), n=10 , p=0.5
