Hey there!
Basically the mean is the average of your given set that you have!
Here is your formula:
mean = SUM of each over your terms DIVIDED BY NUMBER of terms
“15, 8, 12, 14, 10,13”
SUM = addition
15 + 8 + 12 + 14 + 10 + 13
15 + 8 = 23
23 + 12 + 14 + 10 + 13
23 + 12 = 35
35 + 14 + 10 + 13
35 + 14 = 49
49 + 10 + 13
49 + 10 = 59
59 + 13 = 72
72 / NUMBER OF TERMS
Number of terms: 6
72 / 6 = 12
Thus your answer your answer: 12 ☑️
Good luck on your assignment and enjoy your day!

The answer is A because there is a higher chance of the number cube rolling a 3,4,5 or 6 than the cube rolling a 1 or 2. It’s 4 against 2
