Question

A magician showed a magic trick where he picked one card from a standard deck. What is the probability that the KING card will be picked?​

Answer 1

`(1)/(13)`

Explanation:

The total number of cards in a standard deck of cards is 52, in which there:

King: 4 cards <----------

Queens: 4 cards

Jack: 4 cards

Ace: 4 cards

Club/Diamond/Heart/Spade: 13 cards

Moreover, 26 of the 52 cards are red, and the remainder 26 are of black.

So the probability that a "king" card will be picked is
`(4)/(52)`, which can be further simplified
`(1)/(13)`
