[obm-l] Probabilidade - Ducks and hunters
Não tenho nem idéia de como começar, só entendi que o número de ducks
num flock é Poisson(6). Alguém arrisca?
"Ten hunters are waiting for ducks to fly by. When a flock of ducks
flies overhead, 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 hit. Assume that the number of ducks in a flock
is a Poisson random variable with mean 6." (A First Course in Probability)
Agradeço desde já.
