This video shows you how to do a mathematical representation on computing the nCr function using a TI-89 calculator. The formula for a combination is. 5 nCr 3means 5 choose 3.
Then enter the number 2 then press enter key.
From 5 people 2 will be selected as members of a committee. The formula for a combination is. Press the number on the menu that corresponds to the template you want to insert. Were going to assume that you already know how to determine whether or not a probability experiment is binomial and instead just focus on how to use the calculator itself.
