@ Mr. DumbCow
Will you take a look at these (similar to others you've done tonight)? Thanks.

Assume that you have 5 different types of
vegetables and 10 different types of fruit. A vegetable salad consists of a mixture of any 3 types of vegetables, and a fruit salad consists of a mixture of 2 kinds of fruit.
(1) In how many different ways can you prepare
a vegetable salad and a fruit salad?
(2) In how many different ways can you prepare
a vegetable salad or a fruit salad but not both?
(3) How many ways can you choose two different
kinds of salad?

Best ResponseYou've already chosen the best response.0#3 First, we need to determine the number of vegetable and fruit salads possible which is C(5,3) and C(10,2) receptively. Then the product should give the right answer.

Best ResponseYou've already chosen the best response.0395 is wrong and so is 2!*C(5,3)*C(10,2)

Best ResponseYou've already chosen the best response.5This question is poorly worded when solvers have to "guess" what the question author means to say. @ Mr. Fool for Math  I don't know but will work on it.
