The PMF of the experiment that records the number of heads in four flips of a coin, which can be obtained with the R commands attach (expand.grid (X1=0:1, X2=0:1, X3=0:1, X4=0:1)); table(X1+X2+X3+X4)/length(X1), is
| x | 0 | 1 | 2 | 3 | 4 |
| p(x) | 0.0625 | 0.25 | 0.375 | 0.25 | 0.0625 |
Thus, if the random variable X denotes the number of heads in four flips of a coin then the probability of, for example, two heads is P(X = 2) = p(2) = 0.375. What is P(X ≥ 2), that is, the probability that the number of heads will be at least 2?

You flip a coin 100 times. Let X= the number of heads in 100 flips. Assume we don’t know the probability, p, the coin lands on heads (we don’t know its a fair coin). So, let Y be distributed uniformly on the interval [0,1]. Assume the value of Y = the probability that the coin lands on heads. So, we are given Y is uniformly distributed on [0,1] and X given Y=p is binomially distributed on (100,p). Find E(X) and...

An experiment is performed with a coin which has a head on one side and a tail on the other side. The coin is flipped repeatedly until either exactly two heads have appeared or until the coin has been flipped a total of six times, whichever occurs first. Let X denote the number of times the coin is flipped. The probability that the coin comes up heads on any given flip is denoted as p. For parts (a) to (e),...
