9. A card is drawn from a pack of well – shuffled playing cards. Find the probability that the card draw is,(iii) a king (iv) an ace or a queen

(iii)

The probability that getting a king,

In playing cards there are kings,

Therefore, the number of favorable outcomes to the event getting a king

Thus,

P(card drawn is a king) = Favorable outcomes/Total number of outcomes

(iv)

The probability that getting an ace or a queen,

In playing cards there are ace and queens,

Now, the number of favorable outcomes to the event getting an ace or a queen

Thus,

P(card drawn is an ace or a queen) = Favorable outcomes/Total number of outcomes
