A basketball player has a constant probability of 0.4 of making any given shot, independent of previous shots. Let an be the ratio of shots made to shots attempted after n shots. The probability that a10 = 0.4 and an ≤ 0.4 for all n such that 1 ≤ n ≤ 9 is given to be p^aq^br/s^c where p,q,r and s are primes, and a, b, and c are positive integers. Find (p+q+r+s)(a+b+c)
