Kim and Sam are studying the outcomes of flipping a fair coin (equal probability flipping "heads" or "tails"). The coin is flipped 10 times and the number of "heads" is counted. What is the expected number of heads? What is the standard deviation for the number of heads? What is the probability of exactly 5 heads? What is the probability of anything but 5 heads?
