![Vinay and Mahesh alternate playing at the casino table. (Vinay starts and plays at
odd times i = 1,3, ... ; Mahesh plays at even times i =

Assume that the net gains at different times are independent. We refer to an
outcome of-2 as a "loss."
a. They keep gambling until the first time where a loss by Mahesh
immediately follows a loss by Vinay. Write down the PMF of the total
number of rounds played. (A round consists of two plays, one by Vinay and
then one by Mahesh.)
b. Write down the PMF for Z (number of trials), defined as the time at which
Mahesh has his third loss.
c. Let N be the number of rounds until each one of them has won at least
once. Find E[N].](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fa613da6f-cf17-4e21-a42e-2b8268c80420%2Fe47e1336-85e6-43c6-9324-7b5249060d48%2Fl47nyb_processed.jpeg&w=3840&q=75)
