Question

A restaurant serves 8 fish entrees, 12 beef and 10 poultry. If customers select from these entrees randomly, what is the expected number of fish entrees ordered by the next four customers?

Answer 1

There are 8 fish entrees--so the expected number of fish entrees ordered by the next 4 customers is 960?

Answer 2

...doesn't make sense

Answer 3

ok.. a little probability

so P(fish) = 8/30

P(fish, fish, fish , fish) = 8/30 x 8/30 x 8/30 x 8/30

Answer 4

Okay, that makes more sense. Thank you
