Communication Systems - Engineering

Q1:

During transmission over a communication channel, bit errors occur independently with probability P. If a block of n bits is transmitted, the probability of at most one bit error is equal to

A 1 - (1 - P)n

B P + (n - 1) (1 - P)

C nP (1 - P)n - 1

D (1 - P)n + nP (1 - P)n - 1

ANS:A - 1 - (1 - P)n

I think option D is the right answer.
