Answer 1

Answer:

66.67

Step-by-step explanation:

Total number of people writing exam= 30

Number of people failed= 10

Number of people passed= 30–10=20

Percentage= (Number of favorable outcomes/Total number of outcomes)*100%

% of people passed=(20/30)*100

= 2000/30= 66.67%

So,the percentage of people passing in the exam=66.67%
