12. Five mark example problem

In a recent year, of the \(1184\) centum scorers in various subjects in tenth standard public exams, \(233\) were in mathematics, \(125\) in social science and \(106\) in science. If one of the student is selected at random, find the probability of that selected student:

 

(i) is a centum scorer in mathematics \(=\) $\frac{i}{i}$

 

(ii) is not a centum scorer in science \(=\) $\frac{i}{i}$
