A block of 100 bits is transmitted over a binary communication channel with probability of bit error p = 10^-2.
(1) If the received block has 1 or fewer errors then the receiver accepts the block. Find the
probability that the block is accepted after the first transmission.
(2) If the received block has more than 1 error, then the block is retransmitted. Find the
probability that M retransmissions are required before the block is accepted.
