Question
All red face cards are removed from a pack of playing cards. The remaining cards are well shuffled and then a card is drawn at random from them. Find the probability that the drawn card is a red card
Solution
There are 44 identical cards with figure of circle or square in the bag.
∴ Total number of outcomes = 44
There are 20 squares on the cards.
So, the favourable number of outcomes is 20.
∴ P(card drawn has the figure of square) =\[\frac{\text{Favourable number of outcomes }}{\text{ Total number of outcomes }} = \frac{20}{44} = \frac{5}{11}\]
