My son's drawer has 3 black socks and 2 white socks. He cannot understand that, when eyes closed and tries to get a pair, why in 1st attempt same color pair is never found, it is usually mismatched. what he does if pair is mismatched he throws back in the drawer ! He has asked me this few times.. I cannot answer him ...( we are not color blind!) thank you. Rodney

01. I think this is not real-analysis. 2. Draw a small tree chart and mark all cases you have and you already solved this. (Consider the probabilitys are not all equal) – 2011-06-25

2Note that the probability of a match is not dramatically less than $1/2$. Perhaps the "usually mismatched" perception comes from the fact that we remember mismatches more than matches, just like we remember wrong weather forecasts more than right ones. – 2011-06-25
