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

red face cards are 3.So these card get 6 times
Then probability =
52
6
=
26

(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

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

52
4
