Question

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

• A.
• B.
• C.
• D.

Answer 1

The correct option is C

Out of 5 horses, only one is the wining horse. The probability that Mr. A selected that losing horse is $\frac{4}{5}\times \frac{3}{4}$.Therefore, the required probability is
$1-\frac{4}{5}\times \frac{3}{4}=1-\frac{3}{5}=\frac{2}{5}$
