Question

A card is drawn from a pack of 52. How do you find the probability of that card to be an Jack or a King?

Answer 1

`2/13`

Explanation:

A standard pack of playing cards has 4 suits. Hearts, Diamonds, Spades and Clubs. Each suit has 13 cards, numbered 1 - 10 and 3 face cards. King, Queen and Jack.

Total cards in a pack `=4xx13=52`

and `4xx2=8larr" Kings and Jacks"`

`"Probability" ="number of favourable outcomes"/" total number of possible outcomes"`

Favourable outcomes = 8 ( King / Jack) and total number of possible outcomes = 52

`rArrP(K orJ)=8/52=2/13`
