Answer:

The probability of not drawing blue is 0.3

Step-by-step explanation:

The bag contain a total of:

Blue marbles + green marbles + red marbles

= 777 + 222 + 111

= 1110

We are to find the probability of not drawing a blue marble, if a blue marble is not drawn then the drawn marble is either green or red marbles

P(not draw blue) = p(draw green) + p(draw red)

P(not draw blue) = 222/1110 + 111/1110

P(not draw blue) = 333/1110

P(not draw blue) = 0.3
