1.	There are three letters and three corresponding envelop. If each of all the letters are kept randomly in envelop, then what will be the probability that all the letters are kept in right envelops ?
Answer» Total ways to kept 3 letters in 3 envelops ∴ Probability of kept the letter in right way = 1/31 = 1/(3 x 2) = 1/6 Thus Prob. of kept the letter in wrong way = 1 – 1/6 = 5/6

There are three letters and three corresponding envelop. If each of all the letters are kept randomly in envelop, then what will be the probability that all the letters are kept in right envelops ?

Answer»

Total ways to kept 3 letters in 3 envelops

∴ Probability of kept the letter in right way = 1/31

= 1/(3 x 2) = 1/6

Thus Prob. of kept the letter in wrong way

= 1 – 1/6 = 5/6
