9. Suppose that 10 fish are caught at a lake that contains 5 distinct types of fish.

(a). How many different outcomes are possible, where an outcome specifies the numbers of caught fish of each of the five types?

(b). How many outcomes are possible when 3 of the 10 fish caught are trout?

(c). How many when at least 2 of the 10 are trout?

hi any hint how i can solve this question.

What have you thought about or tried, so far?

For example, in part (a), would you be counting combinations or permutations? Are repeats allowed, or not?

Can you explain why you're stuck?

Also, be sure to read the forum guidelines. Thank you! :cool:
