# Problem 1

In drawing 2 cards from a pack of cards, the total number of possible out comes

# Solution

Total number of cards in the pack

= 52

Number of cards drawn

= 2

Experiment :

Drawing 2 cards from the pack of cards

Total Number of Possible Choices

= Number of ways in which 2 cards can be drawn from the 52 cards

⇒ n = 52P2
=
 52 × 51 2 × 1
= 26 × 51
= 1,326

Solution Ans :
 4 17

# Problem 8

Five cards are drawn at random from a pack. The probability that four of them may have the same face value is
Solution Ans :
 1 833

# Problem 9

Define the Event and identify the number of favourable choices in the following
1. From a normal pack of cards 4 are drawn. Find the probability that they are different suits?
2. While shuffling a pack of 52 cards, 2 are accidentally dropped. Find the probability for two missing cards to be of different colours (colors may be taken as red and black)
3. Two cards are drawn simultaneously from a pack. The probability that at least one of them will be the ace of hearts is
4. Two cards are drawn from a pack. Find the probability that one of them is a club and the other is not a club.
5. Two cards are drawn simultaneously from the same set. Find the probability that none of them will be the ace of spade
Solution Ans : 1) 28,561, 2) 676, 3) 51, 4) 1,275, 5) 507
