They are dependent events, because the probability of the second event depends on the result of the first event
If you replace the marble before picking up the second marble, then the first event didn't affect the second result ant the events were independent.
Given that you did not replace the marble, the second pick up has different probailities depending on the first result.

Answer:
$163,002
Step-by-step explanation:
If you're working problems of this sort, you have been shown formulas and examples. Use the appropriate formula with the numbers of this problem.
For the formula below, you have d=3000, r=0.045, k=4, N=11
P = (3000)(1 -(1 +0.045/4)^(-11·4))/(0.045/4) ≈ 163,002
The account needs to hold about $163,002 to make this possible.
Answer: $264
Steps:
1. Change 20% into a decimal. by moving decimal two places to the left.
.20
2. 330 * .20 = 66
20% of 330 is 66 meaning $66 will be discounted from the tv’s original price.
3. 330 - 66 = 264
330 - original price of tv
20% (.20) - discount
264 - price of tv after discount
Equation used to solve: 330 - (330 * .20)
Answer:
b. 3x
Step-by-step explanation:
(3x - 3) + 3 = 3x - 3 + 3 = 3x
4x+7=5x-4
-4x -4x
7=x-4
+4 +4
11=x
