DingProof Posted August 7, 2005 Share Posted August 7, 2005 A man has 8 pairs of gloves with each pair having different colors (8 different colors altogether). If he selects 2 gloves (one at a time without replacement) what is the probability that the 2 gloves will be of the same color? Quote Link to comment Share on other sites More sharing options...
sourabh Posted August 7, 2005 Share Posted August 7, 2005 = 8/16 * 1/15 = 1/30 Quote Link to comment Share on other sites More sharing options...
Dimas Posted August 7, 2005 Share Posted August 7, 2005 1 * 1/15 = 1/15. The first glove can be 'any one'. The second one must belong to the same pair. Quote Link to comment Share on other sites More sharing options...
arjmen Posted August 7, 2005 Share Posted August 7, 2005 Agreed with Dimas. (8C1)/(16C2) = 1/15 Quote Link to comment Share on other sites More sharing options...
