You are playing a game where you draw a card from a standard deck, and you will win $7 if you draw a face card, $6 if you draw an ace and lose $2 if you draw any other card. Complete the probability distribution table. Let x be the winnings (which could be negative in the case of a loss). Remember to list the P(x) as a probability, not a percent. This problem is from the player's point of view. Card Face Ace Anything else $ x P(x) What is the expected gain from this game?
Internet Use in 2000 The following pie chart shows the percentage of the population that used the Internet in 2000, broken down further by family income, and based on a survey taken in August 2000.t $35,000: Nonuser 24% $35,000: 30% Internet user 35% (a) Determine the probability that a randomly chosen person was an Internet user, given that his or her family income was at least $35,000. (Round your answer to two decimal places.) (b) Based on the data, was a person more likely to be an Internet user if his or her family income was less than $35,000 or $35,000 or more? (Support your answer by citing the relevant conditional probabilities. Round your answers to two decimal places.)

A deck of four (4) cards has exactly one (1) color printed on each face – blue, yellow, red, or green. You have two (2) identical decks of this type. In this game, you randomly select a card from each of the two decks. Your score is the number of blue cards drawn – refer to this quantity as X. The probability distribution is below: X P(X) 0 0.5625 1 0.375 2 0.0625 What is the probability that zero blue cards are drawn?
