The mean is the average. You find it by adding all of the numbers in your set together, and then dividing that sum by the number of numbers that you have. For example, this is my set:
12 32 11 8 24
I would add those number together
12 + 32 + 11 + 8 + 24 = 87
Then I would divide 87 by the number of numbers I have, which, in the examples case is 5.
Step-by-step explanation: Just divide the total amount of computer by the probability, which is 287. then you get 29.83, after that just round to the nearest whole number.
