To solve the inequality \(3(b-4)+2b>3\), we first simplify the left-hand side.

1. Distribute the 3:

\[
3(b - 4) = 3b - 12
\]

2. Substitute this into the inequality:

\[
3b - 12 + 2b > 3
\]

3. Combine like terms:

\[
(3b + 2b) - 12 > 3 \quad \Rightarrow \quad 5b - 12 > 3
\]

4. Now, add 12 to both sides:

\[
5b > 3 + 12 \quad \Rightarrow \quad 5b > 15
\]

5. Finally, divide both sides by 5:

\[
b > 3
\]

Now, the solution set is all values of \(b\) that are greater than 3. In set notation, this is expressed as:

\[
(3, \infty)
\]

Therefore, the correct set notation expressing the solutions is:

\[
\boxed{(3, \infty)}
\]
