Question

In a co-education Instituation , out of 200 students 150 were boys. They took an examination and it was found that 120 passed , 10 girls failed . is there any association between gender and success in the examination?​

Answer 1

Answer:

Step-by-step explanation:

Total no.of students=200

Boys=150

So ,  girls=50

120 Passed

So, 80 failed.

Out of 80 - 10 r girls and 70 r boys

Percentage of boys passed=  80*100/150=53.34%

Percentage of girls passed=   40*100/50= 80%

GIrls to boys ratio : 50:150 = 1:3

Success ratio between boys and girls : 3:2

Hope this helps!!!!
