The probability of drawing exactly one red ball is given by:

the probability of drawing two red balls is given by:

The probability of drawing at least one red ball is:
P(1 red ball) + P(2 red balls) = 16/28 + 6/28 = 11/14.
The answer is

Answer:
215
Step-by-step explanation:
subtract 30 from 225
X + y = 12 / x (-45);
Then, -45x - 45y = -540;
We have 80x + 45y = 645 and
-45x - 45y = -540
________________
35x = 105;
Finally, x = 105÷35;
x = 3;
y = 12 - 3;
y = 9;
