Question

A coin that comes up heads with probability p is flipped n consecutive times.

What is the probability that starting with the first flip there are always more heads

than tails that have appeared?

Answer 1

Answer #1

A coin that comes up heads with probability p is flipped n consecutive times.

To calculate : the probability that starting with the first flip there are always more heads than tails that have appeared.

Now,

Let X be the number of heads observed in n flips.

number of heads more than tails is X >= n + 1

You suspect that a coin is biased such that the probability heads is flipped (instead of tails) is 52%. You flip the coin 51 times and observe that 31 of the coin flips are heads. The random variable you are investigating is defined as X = 1 for heads and X = 0 for tails, and you wish to perform a "Z-score" test to test the null hypothesis that H0: u = 0.52 vs. the alternative hypothesis Ha: u > 0.52....

Stacy and George are playing the heads or tails game with a fair coin. The coin is flipped repeatedly until either the fifth heads or the fifth tails appears. If the fifth heads occurs first, Stacy wins the game. Otherwise, George is the winner. Suppose that after the fifth flip, three heads and two tails have occurred. What is the probability that Stacy wins this game?
