9- x=20 20 divided by 2 equals 10. 10+8=18
10- I would say that x=3 because 3x3=9. If you add 9 and 12 together it’s 21. 21 is less than 64.

chance of pulling out a blue marble can be described as 8 equally probable outcomes (blue marbles) out of 20 equally probable outcomes (all marbles).
Similarly, the chance of pulling out a green marble is 5 out of 20.
In total, we have 8*5 (combinations of blue then green) outcomes out of 20*20 (any two marbles):
8*5 / (20*20) = 40 / 400 = 1/10 = 0.1
