प्रश्न
A card is drawn at random form a well-shuffled deck of playing cards. Find the probability that the card drawn is neither a king nor a queen.
उत्तर
Let E be the event of getting either a king or a queen. Then, (not E) is the event that drawn card is neither a king nor a queen.
Then, P(getting a king or a queen ) = `2/13`
Now, P (E) + P (not E) = 1
∴ P(getting neither a king nor a queen ) = `1 - (2/13) = 11/13`
