Answer:
The total combinations are 3
Step-by-step explanation:
The 3 toppings are cherries, sprinkles and chocolate syrup.
Out of these 3, he has to choose any 2.
number of "r" particular things out of "n" things is given by formula
nCr = [tex]\frac{n!}{(n-r)!(r!)}[/tex]
here, n=3 and r=2, so
3C2 = [tex]\frac{3!}{(3-2)!(2!)}[/tex] = 3.
in the above case, the 3 combinations are,
cherries - sprinkles
cherries - chocolate syrup
sprinkles - chocolate syrup
