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
उत्तर
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`
