Question

In a bag there are 44 identical cards with figure of circle or square on them. There are 24 circles, of which 9 are blue and rest are green and 20 squares of which 11 are blue and rest are green.  One card is drawn from the bag at random. Find the probability that it has the figure of square  

Answer 1

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) =

\[\frac{\text{ Favourable number of outcomes }}{\text{ Total number of outcomes }} = \frac{20}{44} = \frac{5}{11}\]
