hello

Coin 1 is biased, with P(H)=0.2; Coin 2 is also biased, with P(H)=0.6; Coin 3 is fair. One of these coins is
randomly selected, and then flipped. Calculate:
a) P(result of the flip is T).
b) P(coin selected was the fair one, if the result of the flip is H).
c) Assuming now that one of the coins is randomly selected and then flipped 2 times,
calculate P(coin selected was the fair one, if result of the flips is TT).

A particular coin is biased. Each timr it is flipped, the probability of a head is P(H)=0.55 and the probability of a tail is P(T)=0.45. Each flip os independent of the other flips. The coin is flipped twice. Let X be the total number of times the coin shows a head out of two flips. So the possible values of X are x=0,1, or 2. a. Compute P(X=0), P(X=1), P(X=2). b. What is the probability that X>=1? c. Compute the...

A black bag contains two coins: one fair, and the other biased (with probability 3/4 of landing heads). Suppose you pick a coin from the bag — you are twice as likely to pick the fair coin as the biased one — and flip it 8 times. Given that three of the first four flips land heads, what is the expected number of heads in the 8 flips?

You select a coin at random: 2/3 of the coins are unfair, 1/3 of the coins are fair. The fair coins are equally likely to flip heads or tails. The unfair coins flip heads 3/4 of the times, and tails 1/4 of the times. You flip the selected coin and get heads or tails. Find (1) the probability that the selected coin is fair given the flip is heads, (2) the probability that the selected coin is fair given the...

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...
