**MathMate**, Sunday, April 17, 2011 at 4:40pmFor flowers, it's out of 9 choose 4, or C(9,4). For foliage, it's 8 choose 3, or C(8,3).

The formula for combinations, C(n,r) is n!/(r!(n-r)!).

For flowers, C(9,4)=9!/(4!5!)=9*8*7*6/(1*2*3*4)=126.

Calculate similarly C(8,3) and multiply the two results together to get the number of different bouquets.
