Each of the integers from 0 to 9, inclusive, is written on a separate slip of blank paper and the ten slips are dropped into hat. If the slips are then drawn one at a time without replacement, how many must be drawn to ensure that the numbers on two of the slips drawn will have a sum of 6?	Choose the correct choice from the following choices
A) 3  B) 4  C) 5  D) 6  E) 7
i'm not sure i got the question right, if it is what i think it is, then 4 should be the right answer   0,1,2, will not have 2 slip sum it 6,add another (either 6,7,8 or 9) and we'll have a pair with sum 6   Ans:4
