The mean is lower than the median because you have 36 and there are 3 numbers with 36 so 3 out of 9 is 1/3 of the qaunitites and you have 20 and 30 which is less than 36 so then when you find it out it will be less than 36
blue marbles - 2/9. red marbles - 3/9 = 1/3 clear marbles - 4/9. Davis got a 2/9 chance and Tessa got a 2/8 or 1/4 chance. I don't know about the last question. it might be 5/9 but I don't know sorry.
