Question
One card is randomly drawn from a pack of 52 cards. Find the probability that: the drawn card is red and a king.
Solution
In randomly drawing a card from 52 cards.
n(s) = 52
Let C denote the event that the drawn card is red and a king.
n(C) = 2
P(C) = ?
n(S) = 52
∴ P(C) = `"n(C)"/"n(S)" = 2/52 = 1/26`.

Sunita choose a card from a well-shuffled deck of 52 cards.
Total number of cards, S = `square`
Let E be the event that the choosen card is a queen.
Number of queens = `square`
Thus, P(E) = `"Number of queens"/"Total number of cards" = square/square = square`
