A box contains 2 coins: one has probability 1/2 of heads, while the other has unknown probability p, 0<=p<=1, of heads. A coin is selected at random and flipped. It is then replaced in the box, and this entire procedure is repeated another time. If 2 heads are observed, what is the value of the maximum likelihood estimator of p?

A) 1/4

B) 1/2

C) 3/4

D) 1

E) doesn't exist

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

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?

coin 1 has probability 0.7 of coming up heads, and coin 2 has probability of 0.6 of coming up heads. we flip a coin each day. if the coin flipped today comes up head, then we select coin 1 to flip tomorrow, and if it comes up tail, then we select coin 2 to flip tomorrow. find the following: a) the transition probability matrix P b) in a long run, what percentage of the results are heads? c) if 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...

Suppose I have two biased coins: coin #1, which lands heads with probability 0.9999, and coin #2, which lands heads with probability 0.1. I conduct an experiment as follows. First I toss a fair coin to decide which biased coin I pick (say, if it lands heads, I pick coin #1, and otherwise I pick coin #2) and then I toss the biased coin twice. Let A be the event that the biased coin #1 is chosen, B1 the event...

Box 1 contains 2 red balls and one blue ball. Box 2 contains 3 blue balls and 1 red ball. A coin is tossed. If it falls heads up, box 1 is selected and a ball is drawn. If it falls tails up, box 2 is selected and a ball is drawn. Find the probability of selecting a red ball.

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....
