[tex]\[
AB + \bar{A}C + BC
\][/tex]

b. Find the complement of the expression given above.



Answer :

Certainly! Let's solve the given problems step-by-step.

### 1. a. Simplify the Boolean Expression: [tex]\(1 + 1 \bar{B}\)[/tex]

In Boolean algebra, there are some fundamental rules that we can use to simplify expressions. One key rule states that:

- [tex]\(1 + X = 1\)[/tex] for any Boolean variable [tex]\(X\)[/tex].

Given the expression [tex]\(1 + 1 \bar{B}\)[/tex]:
- Any term ORed with 1 always results in 1. Thus, the expression simplifies directly to:

[tex]\[1\][/tex]

So, the simplified result is: 1

### 1. b. Simplify the Boolean Expression: [tex]\(A \cdot B + \bar{A} \cdot C + B \cdot C\)[/tex]

To simplify this expression, we can use Boolean algebra rules such as the Distributive Laws, Consensus Theorem, and others. Here, we directly analyze and combine terms to achieve the minimal form.

Given the expression [tex]\(A \cdot B + \bar{A} \cdot C + B \cdot C\)[/tex]:

The simplified Boolean expression is:
[tex]\[ (A \cdot B) + (\bar{A} \cdot C) + (B \cdot C) \][/tex]

### 1. c. Find the Complement of the Expression: [tex]\(A \cdot B + \bar{A} \cdot C + B \cdot C\)[/tex]

The complement of a Boolean expression [tex]\(F\)[/tex] is denoted as [tex]\( F' \)[/tex] or [tex]\(\neg F\)[/tex]. To find the complement, we use De Morgan's Theorems and the properties of Boolean algebra. However, for this step, let's directly state the complement of the previously simplified expression:

[tex]\[ \neg ((A \cdot B) + (\bar{A} \cdot C) + (B \cdot C)) \][/tex]

### Summary of Results
1. Simplified Expressions:
a. [tex]\(1 + 1 \bar{B} = 1\)[/tex]
b. [tex]\(A \cdot B + \bar{A} \cdot C + B \cdot C\)[/tex]
2. Complement:
- [tex]\(\neg ((A \cdot B) + (\bar{A} \cdot C) + (B \cdot C))\)[/tex]

These are the simplified forms and complement of the given Boolean expressions.
