Sum of the probabilities of each outcome in an experiment is...........

Probability of getting 6 with single die is.........

Probability of getting a prime number in single throw of a die is.....

The sum of probabilities of all the outcomes of an experiment is greater than one.

For an event \(E,\ P(\overset { - }{ E } )=1-P(E)\) .

If a Random experiment is performed, then each of its outcome is known as favourable event.

Probability of an event E + Probability of the event 'not E' = --------------

The probability of an event is greater than or equal to __________ and less than or equal to____________

A die is thrown once. Find the probability of getting a number less than 3.

A bag contains lemon flavoured candies only. Malini takes out one candy without looking into the bag. What is the probability that she takes out
(i) an orange flavoured candy?    
(ii) a lemon flavoured candy?

A box contains 5 red marbles, 8 white marbles and 4 green marbles. One marble is taken out of the box at random. What is the probability that the marble taken out will be (i) red? (ii) white? (iii) not green?

A die is thrown once. Find the probability of getting
(i) a prime number.
(ii) a number lying between 2 and 6.
(iii) an odd number

Suppose you drop a die at random on the rectangular region shown in Figure. What is the probability that it will land inside the circle of diameter 1m?

A die is thrown twice. What is the probability that
(i) 5 will not come up either time?
(ii) 5 will come up at least once?
[Hint: Throwing a die twice and throwing two dice simultaneously are treated as the same experiment.]

A card is drawn at random from a pack of 52 playing cards. Find the probability that the card drawn is neither an ace nor a king.

The probability of getting a bad egg in a lot of 800 eggs is 0.125. Find the number of bad eggs in the lot.

A box contains 19 balls bearing numbers 1, 2, 3, ..., 19. A ball is drawn at random from the box. What is the probability that the number on the ball is
(i) a prime number  (ii) divisible by 3 or 5
(iii) neither divisible by 5 nor by 10  (iv) an even number

From a pack of 52 playing cards, jacks queens, kings and aces of red colour are removed. From the remaining a card is drawn at random. Find the probability that the card known is
(i) a black queen (ii) a red card
(iii) a black jack   (iv) a picture card (jacks, queens and kings are picture cards)

From a well-shuffled pack of playing cards, black jacks, black kings and black aces are removed. A card is then drawn at random from the pack. Find the probability of getting
(a) a red card. (b) not a diamond card.

The king, queen and jack of clubs are removed from a deck of 52 playing cards and then well-shuffled. One card is selected from the remaining cards. Find the probability of getting
(i) a heart   (ii) a king   (iii) a club   (iv) the '10' of hearts

In a game, the entry fee is Rs. 5. The game consists of tossing a coin 3 times. If one or two heads show, Shweta gets her entry fee back. If she throws 3 heads, she receives double the entry fees. Otherwise she will lose. For tossing a coin three times, find the probability that she
(i) loses the entry fee
(ii) gets double entry fee
(iii) just gets her entry fee

On the basis of a throw of a pair of dice.
(i)Complete the following table:

(ii)A student argues that there are 111 possible outcomes 2,3,4,5,6,7,8,19,10,11 and 12.Therefore, each of them has a probability\(1\over11\).Do you agree with this argument? Justify your answer.
