Probability Mass Function Question

1. Transmitter transmits with some probabilities of some messages.

P[X=x] = { 1/2, 1/4, 1/8, 1/16, 1/32, 1/64, 1/128, 1/128}

Messages = { I, YOU, WE, ME, THEY, HE, SHE, IT}

Probability is corresponding.

(a) What is the probability that exactly 2 vowels are received when two messages are transmitted.

(b) Probability that out of 5 messages, we have received atleast one H.

(c) On an average, when we Receive 5 messages, what is the expected length of messages.

Question 1 In communications let p denote the probability that a
bit sent by the transmitter will be received erroneously on the
other end of the channel. A telecom company has determined that for
a communication channel an error rate of p > 0.05 is
unacceptable. To perform the test, a predetermined 32 bit long
message is sent (this is a sample with n = 32) and the number of
erroneous bits are counted at the receiving end. The number...

(1) Consider X that follows the Bernoulli distribution with
success probability 1/4, that is, P(X = 1) = 1/4 and P(X = 0) =
3/4. Find the probability mass function of Y , when Y = X4 . Find
the second moment of Y . (2) If X ∼ binomial(10, 1/2), then use the
binomial probability table (Table A.1 in the textbook) to find out
the following probabilities: P(X = 5), P(2.9 ≤ X ≤ 4.9) (3) A deck
of...

Let X be a random variable with probability mass function
P(X =1) =1/2, P(X=2)=1/3, P(X=5)=1/6
(a) Find a function g such that E[g(X)]=1/3 ln(2) + 1/6 ln(5).
You answer should give at least the values g(k) for all possible
values of k of X, but you can also specify g on a larger set if
possible.
(b) Let t be some real number. Find a function g such that
E[g(X)] =1/2 e^t + 2/3 e^(2t) + 5/6 e^(5t)

For problem 1, to compute probabilities, the probability of
event 1 AND event 2 is obtained by multiplying the two
probabilities together, whereas the probability of event 1 OR event
2 is obtained by adding the two probabilities.
1. Duchenne muscular
dystrophy (DMD) is a condition that causes muscle degeneration and
then death. Most people with the condition are wheelchair-bound by
age 12 and dead before age 30.
The condition
is due to a mutation in the gene for...
