(a) Find the probability function of X in terms of p.

(b) The result above can be extended to the case of nindependent tosses (that is, for a generic number of tosses), andthe probability function in this case receives a very specificname. Find the name of this particular probability function.

Notice that the probability of turning up tails in one toss is1−p.
