If two numbers, a and b, are to be chosen from a set of 4 consecutive integers starting with 1 and a set of four consecutive even integers starting with 10, respectively, what is the probability that b/a will not be an integer? Select the correct option:
A) 3/16	B) 1/4	C) 5/16	D) 3/8	E) 1/2
a is from the following set {1,2,3,4}   b is from the following set {10,12,14,16}   The total number of ways of choosing 2 integers, one from each set is  4*4=

16 ways.   The possibilities where b/a is not an integer is for the following outcomes:   {b,a}= {10,3},{10,4},{14,3},{14,4},{16,3} = 5 ways   Thus the probability is 5/16   The answer is 5/16.
