Okay, we have five choices of flavor, chocolate, strawberry, banana, vanilla and mango.
00:06
And it's a three scoop bowl, and they're all different in part a.
00:11
So that means there are five to choose from.
00:15
So 5c, i want three.
00:18
So 5c3.
00:19
There's no order here.
00:20
Simply three scoops of ice cream, but they're all different.
00:25
So 5c is 3.
00:26
I can work out.
00:27
It's 5 factorial over 2 factorial.
00:30
Factorial, which will be 5 times 4 if i cancel out that with that.
00:38
321 cancel out over 2 factorial is 2.
00:43
So the answer here is 10...
