Answer»

The correct ANSWER is (a) 0.6

Explanation: It can be SEEN that the student have scored 3 out of 5 TIMES more than 80 marks.

Therefore, probability that the student has scored more than 80 = \(\frac{number \,of \,occurrence \,of \,EVENT}{Total \,number \,of \,trials}\)

= \(\frac{3}{5}\)

= 0.6.
