Answer:
The no of elements in set A 'n(A)' = 35
Step-by-step explanation:
From the basic relation between two sets A and B we have
[tex]n(A\cup B)=n(A)+n(B)-n(A\cap B)[/tex]
Since it is given that
[tex]n(A\cup B)=50[/tex]
[tex]n(B)=32[/tex]
[tex]n(A\cap B)=17[/tex]
Applying the given values in the above relation we get
[tex]50=n(A)+32-17\\\\\therefore n(A)=50-32+17\\\\\therefore n(A)=35[/tex]
