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.
