We are given three coins: one has heads in both faces, the second has tails in both faces, and the third has a head in one face and a tail in the other. We choose a coin at random, toss it, and the result is heads. What is the probability that the opposite face is tails?

A box contains 4 coins: coin1 has both sides tails; coin2 has both sides heads; coin3 has both sides heads; coin4 is a regular coin (one side heads, one side tails) a) If we randomly choose one coin from the box and flip, what is the probability we get heads? b) Suppose we randomly choose a coin, flip, and get heads. What is the probability that the coin that was chosen is the regular coin?

suppose a box contains three coins. two are fair and one is a coin with two tails. a coin is randomly selected from the box and tossed once. a) what is the probability that the result of the toss is a tail? b) Given the result of the toss is a tail, what is the probability that the selected coin is the one with two tail?

We have two coins whose heads are marked 2 and tails marked 1. One is a fair coin and the other is a biased coin whose probabilities of 'Head' are 1/2 and 1/4 respectively.Suppose we toss the two coins simultaneously. Let S and P be the sum and product of all the outcome numbers on the coins, respectively. 1. Compute the mean and variance of S. Calculate up to 3 decimal places (round the number at 4th place) if necessary....

We toss n coins and each one shows up heads with probability p, independent of the other coin tosses. Each coin which shows up heads is tossed again. What is the probability mass function of the number of heads obtained after the second round of coin tossing?

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...

Part 1. Two fair coins are tossed and we are told that one turned up “Heads”. What is the probability that the other turned up “Tails”? Part 2. Two fair coins are tossed, and we get to see only one, which happened to turn up “Heads”. What is the probability that the hidden coin turned up “Tails”? *Remark This problem is really different from the previous one!

A magician has 20 coins in his pocket. Twelve of these coins are normal fair coins (with one head and one tail) and eight are defective coins with heads on both sides. The magician randomly draws a coin from his pocket and flips it. Given that the flipped coin shows a head, what is the probability that it is defective? Select one: 4/7 8/20 1 1/2
