Rewrite ln(7r 11st) in expanded form.

Stat notes 9/21 nPr= n place r Use when the order of something is important and relevant. nCr= n choose r Use when the order of something is irrelevant, but the overall result is relevant. 1.) A bag contains 10 colored balls, 5 red and 5 green. If you draw 3 without replacement, what is the probability that all three are green Order does not matter here so we’ll be using nCr 10C3 ways to draw 3 general balls out of the 10 5C3 to draw 3 green balls from the bag Poob(3 green balls)= 5C3/10C3= (5x4x3/3x2x1)/(10x9x8/3x2x1)= 1/12 C means n(n1)(n2)... (nr) 2.) You have 10 cards numbered 110. A
