For 6-digit integer 46x,y12, when x and y are drawn at random from {3,5,8}, what is the probability E that the integer drawn is divisible by 8?
* A solution will be posted in two days.  Choose the correct choice from the following.
A) 1/6
B) 1/3
C) 1/2
D) 2/3
E) 5/6
In general, the remainder divided by integer n is the same as the remainder that up to tens of n is divided by 8.   Thus, in order for 46,x,y12 to be divided by 8, y12 should be divided by 8.   Amongst 3,5,8, 3 and 5 can be divided by 8.   Therefore,E= two out of three can be divided and the answer is 2/3.
