Answer:

P(not red marble)=8/11

Step-by-step explanation:

sample space is 110

subtract the red (30)

110-30=80

80/110=8/11

There are a total of 100 marbles (30+20+50).
Of that 100, 70 are not red (50 green + 20 blue).

This means you have a 70/100 chance of pulling something that’s not red.

70/100 reduces down to 7/10 or 70%.
