A word consists of 9 letters; 5 consonants and 4 vowels.Three letters are choosen at random. What is the probability that more than one vowel will be selected ?	Choose the correct choice from the following answers:
A) 17/49  B) 17/42  C) 17/87  D) 17/29  E) 17/12
Explanation:   3 letters can be choosen out of 9 letters in {\color{Black} {^9}C_3} ways.   More than one vowels ( 2 vowels + 1 consonant or 3 vowels ) can be choosen in {\color{17/42lack} \left ( {^4}C_2\times {^5}C_1 \right )+{^4}C_3} ways   Hence,required probability = {\color{17/42lack} \frac{\left ( {^4}C_2\times {^5}C_1 \right )+{^4}C_3}{{^9}C_3}} = 17/42   Answer: 17/42) 17/42
