A coin is flipped. If a heads is flipped, then the coin is flipped 4 more times and the number of heads flipped is noted; otherwise (i.e., a tails is flipped on the initial flip), then the coin is flipped 2 more times and the result of each flip (i.e., heads or tails) is noted successively. How many possible outcomes are in the sample space of this experiment?

(1 point) Rework problem 29 from section 1.4 of your text, involving the flipping of a coin. A coin is flipped. If a heads is flipped, then the coin is flipped 5 more times and the number of heads flipped is noted; otherwise (i.e., a tails is flipped on the initial flip), then the coin is flipped 3 more times and the result of each flip (i.e., heads or tails) is noted successively. How many possible outcomes are in the...

A card is drawn from a standard deck of 52 playing cards. If the card is a club, a fair coin is flipped 7 times and the number of heads flipped is noted. If it is not a club, the coin is only flipped 3 times, but this time the result of each flip is noted. The card drawn is not noted in either case. How many elements are in the sample space for this experiment? I come up with...

When coin 1 is flipped, it lands on heads with probability   3 5  ; when coin 2 is flipped it lands on heads with probability   4 5  . (a) If coin 1 is flipped 11 times, find the probability that it lands on heads at least 9 times.

Deriving fair coin flips from biased coins: From coins with uneven heads/tails probabilities construct an experiment for which there are two disjoint events, with equal probabilities, that we call "heads" and "tails". a. given c1 and c2, where c1 lands heads up with probability 2/3 and c2 lands heads up with probability 1/4, construct a "fair coin flip" experiment. b. given one coin with unknown probability p of landing heads up, where 0 < p < 1, construct a "fair...

Consider a game in which a coin will be flipped three times. For each heads you will be paid $100. Assume that the coin comes up heads with probability ⅔. a. Construct a table of the possibilities and probabilities in this game. The table below gives you a hint on how to do this and shows you that there are now eight possible outcomes. (3 points) b. Compute the expected value of the game. (2 points) c. How much would...
