The mean of this discrete random variable is 7.96
<em><u>Solution:</u></em>
Given that,
x 4 6 9 11 15
P(x) 0.20 0.34 0.15 0.22 0.09
<u><em>Mean is given as:</em></u>
![\mu_{x}=\sum[x \times P(x)]](https://tex.z-dn.net/?f=%5Cmu_%7Bx%7D%3D%5Csum%5Bx%20%5Ctimes%20P%28x%29%5D)
Therefore,

Thus, mean of this discrete random variable is 7.96
