four 6 faced dice are thrown together . the probability that all the four show the same number on them is ?
"it all 4 numbers have to be same basically we want quadruplets . 1111 , 2222 , 3333 , 4444 , 5555 and 6666 . those are six in number . further the four dice can fall in 6 * 6 * 6 * 6 = 1296 ways . hence the probability is 6 / 1296 = 1 / 216 answer : b"
