2.(a) In a series of independent tosses of a coin, with probability p of the coin landing 'heads',and probability 1-p of it landing 'tails', obtain an expression for Pr(X = x),1,2,3,..., where X is a random variable denoting the number of tosses until the firsthead appears.x =(b) If m is a positive integer, obtain an expression for Pr(Y = y), y = m,m +1, m+2, ..where Y is a random variable denoting the number of tosses until the mth head appears.
