[Akshay karpe]

Question 101 

Best fit line is having minimum SSE, So i get 75 for both a & c option. as it is mcq question i selected A option. My request is please give the marks for both a & c option. How many u agree? Please correct answers by iitm team

and also question 93  

4option S2=S3 is incorrect because Cardinality of S2 =2  & S3 = 4 , So only 2 & 3 option are correct

[Shinas MN]

I agree on Q.no 93

[Aritra Roy]

Yeah. How can option 4 : S2=S3 of Q.93) be correct? Please explain. Even I had selected option 2,3 only.

Hi,

For S3, domain is R\Q, so it will exclude 3, -3. So, | S2 | = | S3 | .

Okay so in the third set, the condition R~Q excludes the rational values of x in the equation, leaving us with only the elements which are also in set 2.
