Solution:

Given:
Total number of letters in words = 10
Total number of vowel = 3
Total number of consonant = 7
Formula used:
Probability of getting favorable outcome = (Number of favorable outcomes)/(Total number of outcome)
Calculation:
Total number of letters words = 10
Total number of consonant = 7
Probability of getting consonant = (Total number of a consonant)/(Total number of letter in a word)
⇒ Probability

= 7{/}10

∴ The probability that the letter chosen is a consonant is $7{/}10$ .
