The zebra plays a game in which in every turn she randomly chooses a letter from the set {A,B,C},independently of other turns, and registers the outcome in a list.1. Assume that the zebra plays exactly 4 turns, and let X denote the number of distinct outcomes sheregisters.2. The first moment of X is3. The probability that both A and B are registered at some point during the 4 turns she plays is4. The second moment of X is2. Now assume that the zebra plays until she registers every possible outcome at least once, that is, once shehas registered at least one of each of the outcomes she stops. The expected number of turns she plays is

Figure shows a U.S. roulette wheel that has 38 numbered slots 1 through 36, 0, and 00. Of the 38 compartments, 18 are black, 18 are red, and 2 are green.A play has the dealer spin the wheel and a small ball in opposite directions.As the ball slows to a stop, it can land with equal probability on any one of the 38 numbered slots. Find the probability of red occurring on two consecutive plays.
Experimental or Observational: A group of students is interested in knowing if the number of times they can sink a basketball is related to the color of the basketball. The students shoot a series of baskets and record their success using a regulation colored basketball. They then switch to a blue colored basketball and shoot the same series of baskets. .
