There 13 letter in the word, with 6 vowels and 7 consonants.
One letter is selected out of 13 in 13C1 = 13 ways.
1. One vowel is selected out of 6 in 6C1 = 6 ways.
Thus the probability of a vowel = \(\frac{6}{13}\).
2. One consonant is selected out of 7 in 7C1 = 7 ways.
Thus the probability of a consonant = \(\frac{7}{13}\).
