Question 375949: copykwik has 4 photocopy machines: A,B,C,D the probability that a given machine will break down on a particular day is
P(A)= 1/50 P(B)= 1/60 P(C)= 1/75 P(D)= 1/40
assuming independence what is the probability on a particular day that
a) all four machines will break down
b) none of the machines will break down
