X 1 2 3 4
p(x) 0.40 0.20 0.15 ?
If the items are only 4. The total of the probability must be 1 or 100%
1 - 0.40 - 0.20 - 0.15 = 0.25
The probability of 4 is 0.25.
Average rate of change of the function: 
Step-by-step explanation:
The average rate of change of a function f(x) can be calculated as:
where:
are the x-values of the interval taken into account to evaluate the rate of change of the function
are the values of the function at those points
In this problem, we have:
The function is 
, so
So, the average rate of change in this interval is:
