10th Class Mathematics Probability Question Bank Case Based (MCQs) - Probability

The probability that the arrow will point a perfect square number is:

A) \[\frac{2}{5}\]

B) \[\frac{3}{5}\]

C) \[\frac{1}{2}\]

D) \[\frac{7}{10}\]

Correct Answer: B

Solution :

The total number of possible outcomes = 10 Favourable outcomes \[=[4,9,16,25,36,49]\]

\[\therefore \] Number of favourable outcomes = 6

\[\therefore \] Required probability \[=\frac{6}{10}=\frac{3}{5}\]

So, option [b] is correct.
