Answer: 8/33
Step-by-step explanation:
So the probability of picking a purple marble is 8/12, after that there are 11 marbles left in the box
Now the probability of picking a green marble without placing the first marble back is 4/11
So the probability of doing both is 8/12 x 4/11 = 8/33
(16+5)4÷2=42
21×4÷2=42
84÷2=42
42=42
that is were to but you answer
14n=-126
/14 /14 divide by 14 on both sides of the
equation
n=-9
