Question

If a letter is choosen randomly from all the letters of the word 'MAINTAINANCE', what is the probability that the choosen letter is a consonant

Answer 1

Total number of letters = 12

Let F represent the case where the chosen letter is a consonant.

Here, consonants are M, N, T, N, N, C.

∴ Number of consonants = 6

Thus, P(E) = `"Number of consonants"/"Total number of letters"`

= `6/12`

= `1/2`
