Question 755038: Let us say, for example, that I decide to make the final grading for this class random. I put into a bowl the following: 5 pieces of paper with "A", 2 pieces of paper with "B" and 3 pieces of paper with "C". If I randomly draw once piece of paper from the bowl to determine your final grade, what is the probability that your grade is either an A or a C?

There are 5+2+3 = 10 pieces of paper total

There are 5+3 = 8 pieces of paper that have A or C on it.

So the probability is 8/10 = 4/5
