Robbie has pulled 18 marbles from a large bag, and 9 of them are orange. What is the experimental probability that the next marble selected from the bag will be orange?

18 have been selected.....9 have  been orange.....so we expect that the probability that the next marble is orange  is 9/18  = 1/2
