in a certain lottery , the probability that a number between 1 and 15 , inclusive , is drawn is 1 / 3 . if the probability that a number 1 or larger is drawn is 2 / 3 , what is the probability that a number less than or equal to 15 is drawn ?
n0 = 1.0
n1 = 15.0
n2 = 1.0
n3 = 3.0
n4 = 1.0
n5 = 2.0
n6 = 3.0
n7 = 15.0
t0 = n0 / n3
t1 = n5 / n3
t2 = n0 + t0
answer = t2 - t1
