Consider a coin with probability q of landing on heads, and
probability 1−q of landing on tails.
a) The coin is tossed N times. What is the probability that the
coin lands k times on heads.
b) The coin is tossed 100 times, and lands on heads 70 times. What is the maximum likelihood estimate for q?

Problem 2: Tails and (Heads or Tails?) Alice and Bob play a coin-tossing game. A fair coin (that is a coin with equal probability of 1. The coin lands 'tails-tails' (that is, a tails is immediately followed by a tails) for the first 2. The coin lands 'tails-heads (that is, a tails is immediately followed by a heads) for the landing heads and tails) is tossed repeatedly until one of the following happens time. In this case Alice wins. first...

A jar contains 100 coins, where 99 are fair, but one is double-headed (always landing heads). A coin is chosen randomly from the jar. Then, the chosen coin is flipped 5 times. (a) Compute the probability that the coin lands heads all 5 times. (b) Given the coin lands heads all 5 times, what is the probability that the chosen coin is double-headed?
