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
