Question

Five horses are in a race. $Mr.A$ selects two of the horses at random and bets on them. The probability that $Mr.A$ selected the winning horse is

• A. $\frac{4}{5}$
• B. $\frac{3}{5}$
• C. $\frac{1}{5}$
• D. $\frac{2}{5}$

Answer 1

The correct option is D $\frac{2}{5}$

As Mr A selected two horses, one of them should be the winning horse.
So, Probability $=\frac{NumberoffavourableOutcomes}{Totalnumberofoutcomes}=\frac{2}{5}$
