标题请教一机率难题
时间Sat Feb 14 10:20:55 2009
Ten hutners are waiting for ducks to fly by. When a flock of ducks flies
over-head, the hunters fire at the same time, but each chooses his target
at random, independently of the others. If each hunter independently hits
his target with probability 0.6, compute the expected number of ducks that
are hunt. Assume that the number of ducks in a flock is a Poisson random
variable with mean 6.
恳请赐教
