(b) both partners celebrated their birthday on the same day of the year. State your assumptions
When three friends go for coffee, they decide who will pay the check by each flipping a coin and then letting the 鈥渙dd person鈥� pay. If all three flips produce the same result (so that there is no odd person), then they make a second round of flips, and they continue to do so until there is an odd person. What is the probability that
How many people are needed so that the probability that at least one of them has the same birthday as you is greater than ?
An urn initially contains one red and one blue ball. At each stage, a ball is randomly chosen and then replaced along with another of the same color. Let X denote the selection number of the 铿乺st chosen ball that is blue. For instance, if the 铿乺st selection is red and the second blue, then X is equal to .
In Problem for if the coin is assumed fair, what are the probabilities associated with the values that X can take on?
