Marks: +1, -0

Solution:

Concept:

Probability = (Number of favorable outcomes) / (Total number of outcomes).

Explanation:

The word "HOME" has 4 letters: H, O, M, E.

Vowels: O, E (2 letters). Consonants: H, M (2 letters).

Total ways to choose any 2 letters from 4:

\binom{4}{2} = 6

Favorable ways (both consonants):

\binom{2}{2} = 1

Thus probability =

\frac{1}{6}

Answer:

\frac{1}{6}
