![**Find the mean of the given probability distribution.**
The table shows the probability distribution of a random variable \(x\):
\[
\begin{array}{|c|c|}
\hline
x & P(x) \\
\hline
0 & 0.11 \\
1 & 0.26 \\
2 & 0.35 \\
3 & 0.21 \\
4 & 0.07 \\
\hline
\end{array}
\]
**Options for the mean:**
- 1.87
- 1.78
- 1.57
- 1.68
To find the mean (\(\mu\)) of a probability distribution, use the formula:
\[
\mu = \sum [x \cdot P(x)]
\]
Calculate the mean by multiplying each value of \(x\) by its corresponding probability \(P(x)\), and then summing these products.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Faa92ed72-90bb-4a19-bd9c-370ea9a722ac%2F2e5de745-b99e-4d9a-9ec4-27abce7a6dfc%2Fbh3img9_processed.jpeg&w=3840&q=75)
