0No blue marbles in the bag.
The theoretical probability of randomly picking each color marble is the number of color marbles you have for each color, divided by the total number of marbles. For example, the probability of selecting a red marble is 3/20.
Pr(Red or Blue) = 0.5833...Pr(R on first pull and Blue on second pull) = 0.0533...
15/27. Simply take the probability of drawing a blue marble.

if there is a jar containing 5 red marbles 6green and 4 blue what is the probability off not chossing a blue marble

1/3 or 33%
1 in 3
100%
if you pick one marble at random, the odds are 17/(42+17+27) or 17/86 or about 20%
The probability is 0.56
