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
उत्तर
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`

A bag contains in all 50 balls. Some of them are white, some are blue and some are red. The number of white balls is 11 times the number of blue balls. The number of red balls is less than the number of white balls. Also, the number of red balls is more than the number of blue balls. If one of the balls is selected at random from the bag, what is the probability that it is red ?

In a set of 25 cards, each card bears only one number from 1 to 25. One card is drawn randomly. Write the sample space for this random experiment
Write the event in the set form for the following random experiment. ‘If one die is thrown, the number obtained on the upper face is even.’
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`
Fill in the boxes:

Let F be the event that the choosen card is an eight of the spade.
Number of the eight of the spade = `square`
Thus, P(F) = `square/square`
= `square/square`
