Combinations Homework
Question asked by: WOODSEY16
Asked on: 18 May 2009
There are a huge number of combinations if each person has three options and there are ten people!
The first person could pick colour one two or three, the second person could pick one two or three.
The formula we use is: n!/r!(n-r)!
So this is 10 factorial / 6(7)!
is 10 factorial / 30240 = 120 combinations
