The letters C,K,L and U are rearranged to form the word 'Luck'. Find its probability.  Choices: A) 1/120 B) 1/235 C) 1/24 D) 1/76 E) 1/53
Explanation :   There are total 4 letters. The probability that C gets the first position is 1/4.   The probability that K is in the second position is 1/3.   Likewise, probability for L and U are 1/2 and 1/1.   Hence, the required probability is:-   =&gt; (1/4) x (1/3) x (1/2) x 1.   =&gt; 1/24.   Answer : 1/24
