10C6 = 10!/(6!*(10-6)!) = 10*9*8*7/(4*3*2*1) = 210
There are 210 ways to choose 6 from a group of 10.
Ok so you need to multiply the length, width, and height together for each one.
Bill: 8 x 20 x 6 = 960
Martin: 4 x 15 x 16 = 960
So Bill is right, they both have the same volume.

Answer:
the correct choice is marked
Step-by-step explanation:
The elements are 1, 4, {4}, {9}. That is, any subset that includes 1 must include it without braces. Any subset that includes 9 must include it with braces.
{4, {9}, 1} is a subset of A
7 + (0-7) * 2/3 = 7 - 14/3 = (21 - 14) / 3 = 7/3 = 2.3
