Answer:
[tex]Mean = 1.4[/tex]
Step-by-step explanation:
Given
The table shown above
Required
Determine the mean
Mean is calculated as thus:
[tex]Mean = \sum (x.P(x))[/tex]
In other words, sum the product of corresponding values of x and P(x)
For the given table, we have:
[tex]Mean = 0 * 0.3 + 1 * 0.3 + 2 * 0.1 + 3 * 0.3[/tex]
[tex]Mean = 0 + 0.3 + 0.2 + 0.9[/tex]
[tex]Mean = 1.4[/tex]
Hence, the mean of the distribution is 1.4
