A biased coin has probability p = 3/7 of flipping heads. In a certain game, one flips this coin repeatedly until flipping a total of four heads.

(a) What is the probability a player finishes in no more than 10 flips?

(b) If five players independently play this game, what is the probability that exactly two of them finish in no more than ten flips?

- Your friend claims he has a fair coin; that is, the probability of flipping heads or tails is equal to 0.5. You believe the coin is weighted. Suppose a coin toss turns up 15 heads out of 20 trials. At α = 0.05, can we conclude that the coin is fair (i.e., the probability of flipping heads is 0.5)? You may use the traditional method or P-value method.

A box contains three fair coins and one biased coin. For the biased coin, the probability that any flip will result in a head is 1/3. Al draws two coins from the box, flips each of them once, observes an outcome of one head and one tail and returns the coins to the box. Bo then draws one coin from the box and flips it. The result is a tail. Determine the probability that neither Al nor Bo removed the...
