If two letters are taken at random from the word CANE, what is the probability that none of the letters would be vowels?

OPtion

1) 2/5
2) 3/5
3) 1/2
4) 1/6
5) 1/3
6) 1/12
7) 2/3
8) 3/4
9) 5/12
10) None of these

Solution

P(first letter is not vowel) = 2/4

P(second letter is not vowel) = 1/3

So, probability that none of letters would be vowels is = 2/4×1/3=1/6
