The four separate cases are $\overline{a} \cdot \overline{b} \cdot \overline{c} \quad \overline{a} \cdot b \cdot \overline{c} \quad \overline{a} \cdot b \cdot \mathrm{c}$ Combining them by using the OR operator produces the following Boolean expression: $\overline{a} \cdot \overline{b} \cdot \overline{c}+\overline{a} \cdot b \cdot \overline{c}+\overline{a} \cdot b \cdot c+a \cdot b \cdot \overline{c}$ When this Boolean expression is represented as a Boolean diagram, it appears as follows: $$continue\ solution\ by\ seeing \ the\ following\ image:$$
