Stephen reaches into a bag of marbles and pulls one out at random. What is the probability that he pulls out a marble that is not strippped/swirled?
There are 10 marbles 7 of them are not striped/swirled so that makes it 6/10 marbles are not striped/swirled so the answer would be either 7/10, 70%, 0.7 (there are the same thing)
