Question

Use Karnaugh map to find the simplified expression of the function: F = x’yz + xy + xy’z’.

(a) xz’+y’z’

(b) xy’z+xy

(c) y’z+x’y+z

(d) yz+xy+xy’z

This question was posed to me during an interview.

The query is from Boolean Algebra in portion Boolean Algebra and Modeling Computations of Discrete Mathematics

Answer 1

Correct option is (d) yz+xy+xy’z

Explanation: F = x’yz + xyz + xy z’ + xy’z’ is the canonical form for the function. Now, using k-map the minimal form must be: yz+xy+xy’z.
