Answer:

[tex]E(x) =\sum_{i=1}^n X_i P(X_i)[/tex]

And replacig we got:

[tex]E(x) = 4*0.25 +5*0.6 +6*0.15= 4.9[/tex]

Step-by-step explanation:

For this case we have the following distribution function

x       4        5     6

p(x) 0.25  0.6  0.15

And we want to find the mean of the distributuon and we can use the following formula:

[tex]E(x) =\sum_{i=1}^n X_i P(X_i)[/tex]

And replacig we got:

[tex]E(x) = 4*0.25 +5*0.6 +6*0.15= 4.9[/tex]
