Hi could u please explain it more?
I don't undersatnd why outcomes with g are
6C2-15 ways
6C3-20 ways
6C4-15 ways
For me 15 ways - combinations of any 2 flavours out of 6 (including or excluding g)


Outcomes with g are not 6C2, 6C3, 6C4.

They are ALL possible ways (including g) of containing 2, 3, 4 flavors per box.

To find out the outcomes with g, we have to subtract from the all outcomes the ways in which g is NOT included.

So it'd be:
6C2 - 5C2 = 5
6C3 - 5C3 = 10
6C4 - 5C4 = 10
25 ways in which g is contained.

Total 50 ways, so 25/50 = 1/2.

D :)

I think BG meant "total outcomes". :wink:
