Andy has 20 pairs of matched gloves. If he loses 15 individual gloves, which of the following is NOT a possible number of matched pairs he has left?  Choices: A) 9 B) 11 C) 13 D) 14 E) 15
We can solve this is second. The question isSelect an answer choice where there is no possibility of having a number as a matched pair   Case1: If 15 gloves are gone the maximum probability of losing maximum gloves is 15 pairs of gloves out of 20. This means i m having 5 pairs of gloves. [Minimum number of gloves i can have is 5 pairs]   Case2: If 15 gloves are gone the maximum probability of losing minimum gloves is 15/2=

7.5 means i can lose 8 glove. in this scenario i will be having 12 gloves.   Hence10 &lt; Available Glove Pair &lt; 13   any given time I cant possess 13 glove pair for the above mentioned scenario. And thats the answer. 13.
