Total	-	30	-	-

An expert commille was formed which decide that the following fact were self evident: Half of student's were ether excellent or good. 40% of the student were females. One-third of the male student were average.

What is the proportion of male Student under good category?

0.73

0.41

1.0

✅ Correct Option: 2

Total $=80$ , males $=48$ . Male average $=\frac{1}{3}\times48=16$ , male excellent $=10$ , so male good $=48-16-10=22$ . Proportion of males under good $=\frac{22}{30}\approx0.73$ .
