im looking to verify 2 of my answers here:
there are 4 ice cream flavours and 6 toppings.
how many sundaes are possible using one flavor of ice cream and 3 different toppings?
I got C(4,1)XC(6,3) = 80
B) how many sundaes are possible using one flavor of ice cream and from zero to six toppings.
I got C(4,1) X 6! not too sure about that one
then finally C) how many different combinations of flavors of 3 scoops of ice cream are possible if it is permissible to make all 3 scopps the same flavor.

Your first is right.
The second isn't
It is C(4,1) but now you want the possibility of 0 toppings
C(6,0), or 1 topping C(6,1) or 2 . . . or 6 toppings C(6,6). Spo you have to add all the possibilities with 0 to 6 toppings and multiply b C(4,1)
