I toss an unfair coin 12 times. This coin is 65% likely to show up heads. Since the binomial table only gives up to 50%, I will have to look at probability for tails. Which column will I be looking in (ie. .05, .30, .50...)?

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?

2. Binomial Distribution Suppose I have an unfair coin, it lands on heads 75% of the time. If I flip this coin four times, what is the probability that I will get only 1 heads? What is the mean for number of heads? Variance? Standard Deviation?

One application of an absolute value inequality is the concept of the unfair coin. If a coin is tossed 100 times, we would expect approximately 50 of the tosses to be heads; however this is rarely the case.1. Toss a coin 100 times to test this hypothesis. Record the number of times the coin is heads and the number of times the coin is tails on the lines below. You may want to ask someone to tally the results of...

35. You and I play the following game: I toss a coin repeatedly. The coin is unfair and P(H) = p. The game ends the first time that two consecutive heads (HH) or two consec- utive tails (TT) are observed. I win if (HH) is observed and you win if (TT) is observed. Given that I won the game, find the probability that the first coin toss resulted in heads?

Suppose you have an unfair coin that is weighted so that heads comes up only 30 percent of the time. If you flip the coin 4 times, what is the probability that you obtain at least 3 heads in the 4 flips?

An unfair coin has probability of heads equal to p. An experiment consists of flipping this unfair coin n times and then counting the number of heads. a. Let Y; be a random variable which is 1 if the ith flip is heads and 0 if the ith flip is tails, where 1 sisn. Show that E (Y) = p and V(Y) = p-p2. b. Derive the moment-generating function of Y. c....
