A coin is flipped twice. Let Y = number of heads obtained, when the probability of a head for a flip equals π.

a. Assuming π = 0.50, specify the probabilities for the possible values for Y, and find the distribution's mean and standard deviation.

b. Find the binomial probabilities for Y when π equals (i) 0.60, (ii) 0.40.

c. Suppose you observe y = 1 and do not know π. Calculate and sketch the likelihood function.

d. Using the plotted likelihood function from (c), show that the ML estimate of π equals 0.50.
