Mathematics: Find the mean of following distribution 4. p(x) 0.25 0.15

So you are solving for x so 0.5x-0.75 3.25 add 0.75 to both 0.5x 4.00 divide by .5 or you can times it by 2...

$E(x) =\sum_{i=1}^n X_i P(X_i)$

And replacig we got:

E(x) = 4*0.25 +5*0.6 +6*0.15= 4.9

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:

$E(x) =\sum_{i=1}^n X_i P(X_i)$

And replacig we got:

E(x) = 4*0.25 +5*0.6 +6*0.15= 4.9
