A card is drawn at random from a well-shuffled pack of 52 plating cards. Completer the following activity to find the probability of the events that the card drawn is (a) a king (b) a face card.

Answer

(a) There are 4 cards of king.
`thereforen(A)=4 ;P(A) =(n(A))/(n(S))=4/52=1/13`
(b) There are 12 face cards.
`therefore n(B)=12;P(B)=(n(B))/(n(S))=12/52=3/13`

Explanation

The sample space S contains 52 sample points.
`therefore n(S)=52.`
(a) Let A be the event of getting a king.
There are `square` cards of king `thereforen(A)=square`
`P(A)=(n(A))/(n(S))=-`
(b) Let B be the evetn of getting a face card.
There are `square` face cards. `thereforen(B)=square`
`P(B)=(n(B))/(n(S))=-`
