Question

A jar contains 30 red marbles, 50 green marbles, and 20 blue marbles. What is the probability of getting a

marble that is not red when drawing one at random?

Answer 1

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%.

Answer 2

P(not red marble)=8/11

Explanation:

sample space is 110

subtract the red (30)

110-30=80

80/110=8/11
