Question: Richie has just bought a small bag of Skittles. Not that Richie could know this, but inside are 20 candies, 7 green, 5 orange, 4 red, 3 yellow, and only 1 brown. Richie tear open one corner of the package and begin eating them by shaking out one at a time. What is the probability that Richie's 2 first skittles are both orange? that none of her first 3 candies is green?
