Select
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 13 gloves are gone the maximum probability of losing maximum gloves is 13 pairs of gloves out of 20. This means i m having 7 pairs of gloves. [Minimum number of gloves i can have is 7 pairs]   Case2: If 13 gloves are gone the maximum probability of losing minimum gloves is 13/2= 
<gadget id="calculator">13/2</gadget>
<output>13/2 = around 6.5</output>
6.5 means i can lose 7 glove. in this scenario i will be having 13 gloves.   Hence10 &lt; Available Glove Pair &lt; 14   any given time I cant possess 14 glove pair for the above mentioned scenario. And thats the answer. 14.
