Question

What is the probability that the student has scored more than 80?

(a) 0.6

(b) 0.8

(c) 0.4

(d) 0.5

The question was asked by my school teacher while I was bunking the class.

This is a very interesting question from Probability & Experimental Approach in division Probability of Mathematics – Class 9

Answer 1

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.
