Question

Please help I got one part right and can’t figure out the secs part

Answer 1

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),

`\begin{gathered} 0\cdot0.366=0 \\ 1\cdot0.427=0.427 \\ 2\cdot0.180=0.360 \\ 3\cdot0.027=0.081 \end{gathered}`

2. add the results:

`0+0.427+0.360+0.081=0.868`

rounding to one decimal place, the mean is 0.9
