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`

Fill in the boxes:
Sunita choose a card from a well-shuffled deck of 52 cards.
Total number of cards, S = `square`
Let E be the event that the choosen card is a queen.
Number of queens = `square`
Thus, P(E) = `"Number of queens"/"Total number of cards" = square/square = square`
