Question

xP(x)00.210.320.230.3Find the mean of this probability distribution. Round your answer to one decimal place.

Answer 1

Step-by-step explanation:

Concept:

The mean of a probability distribution is calculated using the fomrula below

`\mu=\sum_^xP(x)`

By substituting the values, we will have

`\begin{gathered} \mu=\sum_^xP(x) \\ \mu=(0*0.2)+(1*0.3)+(2*0.2)+(3*0.3) \\ \mu=0+0.3+0.4+0.9 \\ \mu=1.6 \end{gathered}`

Hence,

The final answer is

`1.6`
