Answer:

[tex]P(\bar E)=\dfrac{7}{9}[/tex]

Step-by-step explanation:

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

[tex]P(E)+P{(\bar E)=1[/tex]

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

We have, P(E) = 2/9

So,

[tex]P{(\bar E)=1-P(E)[/tex]

[tex]\\\\=1-\dfrac{2}{9}\\\\=\dfrac{7}{9}[/tex]

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