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 vowel

Answer 1

Total number of letters = 12

In the event that the chosen letter is a vowel, use E.

Here, vowels are A, I, A, I, A, E.

∴ Number of vowels = 6

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

= `6/12`

= `1/2`
