In order to calculate the mean of the distribution, we need to follow these steps:
1.multiply each value of X by each probability P(X),
[tex]\begin{gathered} 0\cdot0.366=0 \\ 1\cdot0.427=0.427 \\ 2\cdot0.180=0.360 \\ 3\cdot0.027=0.081 \end{gathered}[/tex]
2. add the results:
[tex]0+0.427+0.360+0.081=0.868[/tex]
rounding to one decimal place, the mean is 0.9
