Did I put this truth table in the k-map correctly?

Hello everyone, I need to you to check if i did this right, i did this k-map 3 different times and everytime i do it, i get a different answer. okay here is the picture:

no, you have an error. you have two c' entries on thr map but only one in the original truth table.

[mr_coffee]

so the 1's should be here:
011
101
111
110
right?>

You could simplify using boolean theorems to check your answer.

z= A'BC+AB'C+ABC'+ABC

The last term ABC, has at least two variables common in the other terms.

Z = A'BC+ABC+AB'C+ABC+ABC'+ABC
Z = BC(A'+A) + AC(B'+B) + AB(C'+C)
Z = BC + AC + AB

You have BC + AC' + AB


The mistake that you made in the K-map is that you have AB'C' instead of AB'C.
