Answer 1

Answer:

85%

Step-by-step explanation:

In a class 40%students enrolled for math and 70% of students enrolled for economic, for both 15% of students enrolled, so we can minus from 100 we can get 85%

Answer 2

Percentage of students of the class did not enroll for either of the two subjects would be $100-95=5\%$

Step-by-step explanation:

Since we have given that

Percentage of students in rolled for maths = 40%

Percentage of students for economics = 70%

Percentage of students for both = 15%

So, now,

$P(M\cup E)=P(M)+P(E)-P(M\cap E)\\\\P(M\cup E)=40+70-15\\\\P(M\cup E)=95\%$

So, Percentage of students of the class did not enroll for either of the two subjects would be $100-95=5\%$
