In 52 cards getting a one card as 52 times

a.(1) The king in card is two getting in 2 times

Then probability =

52

2

=

26

1

(ii)In 52 cards the king ,queen and joker are three face card.Then total face cards are 12.So these card get 12 times

Then probability =

52

12

=

13

3

(!!!)In 52 cards the red face card are 3 face card.Then total

red face cards are 3.So these card get 6 times

Then probability =

52

6

=

26

3

(iv)In 52 cards the jack of heart card is one .So the getting time card is one

Then probability =$$\frac{1}{52}

(b) (i)In 52 cards the spade cards are 13. So getting time is 13

Then probability =

52

13

=

4

1

(ii)In 52 cards the queen of diamonds is one .So getting time is one

Then probevility=

52

1

(iii)In 52 cards Neither a red card nor a queen the total cards are

24.So time of getting cards are 24

Then probability =

52

24

=

13

6

(c) (i)In 52 cards non-face cards are 40.So timie of getting cards are 40.

Then probability =

52

24

=

13

6

(ii)In 52 cards a black king or a red queen are 4.So getting time is 4.

Then probability =

52

4

=

13

Answer 2

Answer:

The deck has four suits: spades, clubs,hearts, and diamonds. Each suit has 3 face cards: king, queen and jack. So altogether there are 4 × 3 = 12 face cards in the 52-card deck.

There are different opinions about whether the ace is a picture card. Aces are not included in the answer.

The size of the sample space is 52. Assuming the cards are well-shuffled,

Pr(getting a face card when one card is drawn) = 12/52 =62/6 =3/13
