Question

6 The percentages of marks obtained by a student in six unit tests are
given below:
Unit test
1 II
IV V VI
Percentage of marks obtained
53 72 28 46 67 59
A unit test is selected at random. What is the probability that the
student gets more than 60% marks in the test?​

Answer 1

Answer:

1/3

Step-by-step explanation:

Number of tests which he gets more than 60% is 2

The total number of tests is 6 So we get Required probability = Number of tests which he gets more than 60%/ total number of tests By substituting the values

Required probability = 2/6

On further calculation Required probability = 1/3
