Step-by-step explanation:
The probability can be defined as the ratio between the possible events and the total number of outcomes.
In this case, according to the image attached, the total number of outcomes is 11, because they are 11 marbles in total.

Answer:robert=120lbs,genesis=100
Step-by-step explanation:take genesis as (x) and since robert is 20 pounds heavier he would be (X+20) so:
x+(x+20) =220lbs
2x+20=220
2x=220-20
2x=200
x=100 which we took as genesis
which leaves robert's weight 100 +20 =120
