Shyanne Cherry · Answer 1

The correct answers are: #3) 72; #4) 40,320; #5) 90.

Explanation:

#3) The number of possible choices are found by multiplying the choices of flavors and the choices of toppings:

6*12=72.

#4) The ordering of 8 cards is a permutation, given by 8!=40,320.

#5) This is a permutation of 10 objects taken 2 at a time:

P (10,2) = 10! / (10-2) !=10!/8!=90.
