Consider the following game: We spin the spinner. If the outcome is favorable for E, then we win 1 unit. If the outcome is not favorable for E, then we neither win nor lose anything. Compute the expected value, E.V., for this game and compare it to P(E), which is 60%. You should discover a coincidence that holds for this kind of game, but which is not true for every game.

Problem 1: Game Spinner We will be comparing empirical (relative frequencies based on an observation of a real-life process) to theoretical (long-run relative frequency) probabilities. We will use StatCrunch to simulate this process using a board game spinner three times so that we can determine the total number of spaces moved in three turns. The board game spinner looks like the image below. The spinner is equally likely to land on any given section. f) Calculate the theoretical probability of...

Consider a play of the casino game `Quick Draw'. In this game, a player pays $11 to play. The player picks one card from a standard pack of 52 cards (i.e. there are four A’s and four K’s in a standard pack of 52 cards). If the player gets an Ace, they win $50 but loose the amount they paid to play (the profit is revenue minus cost); if the player selects a King, they win $30 but loose the...

(1 point) A game of chance involves rolling an unevenly balanced 4-sided die. The probability that a roll comes up 1 is 0.21, the probability that a roll comes up 1 or 2 is 0.44, and the probability that a roll comes up 2 or 3 is 0.55 . If you win the amount that appears on the die, what is your expected winnings? (Note that the die has 4 sides.)
