Answer:

$P(\bar E)=(7)/(9)$

Explanation:

If P(E) is the probabillity of geting an event and P(E (not)) is the probability of getting not an event. Then,

$P(E)+P{(\bar E)=1$

We need to find the probability they will not draw a red marble.

We have, P(E) = 2/9

So,

$P{(\bar E)=1-P(E)$

$\\\\=1-(2)/(9)\\\\=(7)/(9)$

So, the probability they will not draw a red marble is 7/9.
