P(2heads) = 1/2 * 1/2 or 1/4
P(1 tail) = 1/2
P(2 heads, 1 tail) = 1/4 * 1/2
P(2 heads, 1 tail) = 1/8

Consider a single tossing of x unbiased coins: a) Find the probability pX(x) of obtaining all heads; [2] b) If x is regarded as a continuous variable in the range 0 ≤ x < ∞, show that pX(x), regarded as a function of x and suitably scaled, determines a probability distribution; [5] c) Obtain a pdf of this distribution and calculate its cumulant generating function; [5] d) Hence or otherwise, show that the mean and variance are 1 ln 2 and 1 (ln 2)2 , respectively. [8] e) Verify that the coefficient skewness for this distribution is γ3 = 2. [5]
