Answer:
4.4
Step-by-step explanation:
The sum of the probabilities of all possible outcomes is 1.
As the die is loaded so that the number 4 occurs 3/10 of the time, and the other numbers occur with equal frequency, then the probability of numbers 1, 2, 3, 5, 6, 7 and 8 being rolled is 1/10.
Create a probability distribution table for X, where X is the score on the loaded 8-sided die:

Add a product row and a totals column:

(The Product is row is the product of the <u>score on the die</u> and <u>its probability</u>).
The expected value (EV) is the sum of the product of each outcome and its probability.
Therefore, the expected value (EV) of this die is 44/10 = 4.4
For this case we must find the area of the cookie, knowing that it has a circular shape. By definition, the area of a circle is given by:

Where:
r: It is the radius of the circle
According to the data we have:

Thus, the area of the cookie is:

We have 

We round:

Thus, the area of the cookie is
