Find the Mean of the Given Probability Distribution A) $\mu = 3.40$

Find the mean of the given probability distribution.
-The random variable x is the number of houses sold by a realtor in a single month at the Sendsom's Real Estate office. Its probability distribution is as follows.

$\begin{array}{c|c}\text { Houses Sold }(\mathrm{x}) & \text { Probability } \mathrm{P}(\mathrm{x}) \\\hline 0 & 0.24 \\1 & 0.01 \\2 & 0.12 \\3 & 0.16 \\4 & 0.01 \\5 & 0.14 \\6 & 0.11 \\7 & 0.21\end{array}$

A) $\mu = 3.40$
B) $\mu = 3.60$
C) $\mu = 3.35$
D) $\mu = 3.50$
