Question

In Boolean algebra, Y = A + B implies that(a) output Y exists when both inputs A and B exist(b) output Y exists when either input A exists or input B exists or both inputs A and B exist(c) output Y exists when either input A exists or input B exists but not when both inputs A and B exist(d) output Y exists when both inputs A and B exists but not when either input A or B exist

Answer 1

b) output Y exists when either input A exists or input B exists or both inputs A and B exists

because Y=A+B represents OR gate
