There are 5 blue shirts and only one is big, so the probability would be 1/12. The percentage would be approximately 8%
PEMDAS = Parentheses, Exponents, Multiplication, Division, Addition, and Subtraction.
So multiplication first, 56*2= 112
Division second, 5/5=1
Subtraction last, so 112 - 1 = 111
111 is the answer.
To find out the average score, all we need to do is to add all the scores and then divide the result by the amount of numbers we added. So in this situation it'll look like this:
(10.2 + 11.4 + 10.5 + 12.6 + 12.2 + 11.6 + 13.1 + 12.8) ÷ 8 =
= 94.4 ÷ 8 =
= 11.8
Answer: Marvin's average score was 11.8.
