can anyone calculate first and follow of this or the question is incorrect ??

Question

calculate first and follow

S -> AB

A -> SD / e

C ->  a / ε

D -> b

or
calculate follow in this

S -> AB

A -> CD

C -> a / ε

D -> b

Comments

Correct, edited my comment as well

So finally our grammer become

P - > S
S  - > A | A ;S
A - > id = E
E - > TE'| (E)E'
E' -> +EE'  | -EE' | *EE' | /EE' | ϵ
T -> id | num

First(E') = {+,-,*,/, ϵ }
Now we can easily find Follow(E) = {$, +,-,*,/,),;}

Removing left recursion made things easy here.
