a bag contains one fair coin, two two-headed coins, and three two-tailed coins. each of the is flipped, but the outcomes of the fice coins are hidden from you, randomly. if the outcome you see is headsm, what is the probability that the fair coin (which may or may not be the coin that was shown to you) panded heads up?

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?

Rosencrantz and Guildenstern are flipping coins. Guildenstern has a bag with 100 coins in it. All of them are fair coins, except for 10 that each have heads on both sides and 2 that each have tails on both sides. Guildenstern reaches into the bag without looking, removes a randomly chosen coin, with each of the 100 coins equally likely, and flips it. Give exact answers expressed as simplified fractions. (a) What is the probability that it is one of...

MATLAB problem
Imagine we have three types of coins in a bag: Fair Coin (FC)
with Pr(Head) = Pr(Tail) = 0.5; Head-heavy Coin (HC) with Pr(Head)
= 0.4; and Tail-heavy Coin (TC) with Pr(Head) = 0.6. A coin is
randomly picked out of the bag. Write a MATLAB code that can
estimate the type of this coin
The result graph should look like this:
Flipping a Fair Coin for 400 Times Fiping a Coin (1 for Head and 0 for...

Tom has three coins. Two are fair and one is unfair coin weighted so that heads is three times as likely as tails. He selects one of the coins at random and flips it. What is the probability it comes up heads? If it does come up heads, what is the probability it was the unfair coin?

6. A bag has 3 type A coins and 2 type B coins. The probability of heads with a type A coin is 1/4 and that with a type B coin is 1/2. A coin is randomly chosen from the bag and tossed. Given that the coin lands heads, what is the probability that it is of type A?

You have 5 coins, four of which are fair coins, i.e. P(H)=P(T)= 0.5, and the other of which is a two headed coin, i.e. both sides have a head. Suppose you select a coin at random and flip in 3 times, getting all heads. If you flip the coin again, what is the probability it will be heads?
