From (1, 2, 3, 4, 5, 6), one number is picked out and replaced and one number is picked out again. If the sum of the 2 numbers is 5, what is the probability that the 2 numbers included the number 3?
Select the correct option.
A) 1/5	B) 1/2	C) 3/10	D) 3/5	E) 1/4
We know that the sum of two numbers picked was 8. So, there could be the following cases:   (1, 4);   (4, 1);   (2, 3);   (3, 2);   Total of 4 cases out of which 2 have 3, thus the probability is 2/4=1/2.   Ans 1/2
