Q.Prepare the truth table for the following Boolean expressions? (1) A.B+Á.B

Question

just tell me what is the ans?

Answer 1

Assuming A.B is the intersection of A and B:

 

A     B     A.B+Á.B

1     0          1

1     1          1

0     0          1

0     1          1

 

*Note, when you have the intersection between boolean sets A and B and the compliment of A with B with an "or" expression (addition), the resulting expression will always hold true (either B intersects A, or its compliment).
