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...

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)
