You have 3 jars. Each jar has a label on it: white, black,
or white&black. You have 3 sets of marbles: white, black,
and white&black. One set is stored in one jar. The labels
on the jars are guaranteed to be incorrect (i.e. white will
not contain white). Which jar would you choose from to give
you the best chances of identifying the which set of
marbles in is in which jar?

Answer Posted / confucious
Label: B W B&W
Case 1
choose B :
possibility of W is (B or B&W) = 50%
possibility of B@W is (B or W) = 50%
Case 2
choose W :
possibility of B is (W or B&W) = 50%
possibility of B@W is (B or W) = 50%
Case 3
choose B&W :
possibility of B is (W or B&W) = 50%
possibility of W is (B or B&W) = 50%
hence i would support DV's opinion
