Question

A card is drawn at random from a well-shuffled deck of playing cards. Find the probability that the card drawn is a black king.

Answer 1

Let S be the sample space of drawing a card from a well-shuffled deck.

`n(S)=""^52C_1=52`

There are 2 black king cards in a deck A card of black king can be drawn in `""^2C_1=2`

Probability of drawing a black king =2/52=1/26
