Question 4

A roadside shop sells minnows to fisherman. The minnows are kept in a large tank (very large population of minnows) and the worker scoops out a cupful to give to the customer. The average number of fish in a cupful is 24. To determine the probability that there will be less than 20 in a cupful, what distribution should be used?

Group of answer choices

Poisson because I can count the minnows that are in the cup but not count the ones that are not there.

Binomial because I know the average rate of fish in a cup.

Hypergeometric because the probabilities will change with each cup drawn.

Poisson estimation of binomial because the sample size is large and probability is small.
