Question 734163: A.)Using 15 flavors of ice cream,
How many different triple cones can be created with 3 different flavors if you specify which flavor goes on bottom, middle and top?
which formula would be used?
B) Using 15 flavors again, how many different triple cones can you create with 3 different flavors if you don't care about the order of the flavors on the cone? For this problem,I think you would
nCr= n!/(n-r)!* r!
=15!/(15-3)!*3!
= 15*14*13*12!/12!*3!
=15*14*13/3*2*1
=2730/6
=455 Is this correct?
