Suppose that balls are put into boxes, with each ball independently being put in box with probability
(a) Find the expected number of boxes that do not have any balls.
(b) Find the expected number of boxes that have exactly ball.

A communications channel transmits the digits and However, due to static, the digit transmitted is incorrectly received with probability Suppose that we want to transmit an important message consisting of one binary digit. To reduce the chance of error, we transmit instead of and 11111 instead of If the receiver of the message uses 鈥渕ajority鈥� decoding, what is the probability that the message will be wrong when decoded? What independence assumptions are you making?
A family has n children with probability where
(a) What proportion of families has no children?
