**Testing Independence of Events C and D**

Examine the pair of events C and D for independence using the following table:

|   | A   | B   | C   | Total |
|---|-----|-----|-----|-------|
| D | 0.18| 0.02| 0.20| 0.40  |
| E | 0.06| 0.10| 0.04| 0.20  |
| F | 0.06| 0.08| 0.26| 0.40  |
| Total | 0.30| 0.20| 0.50| 1.00 |

**Determining Independence**

Are C and D independent or dependent and why? Select the correct answer below and fill in the answer boxes to complete your choice.

**Options:**

- **A.** C and D are dependent because P(C∩D) does not equal P(C)P(D). P(C∩D) = [ ], and P(C)P(D) = [ ].
  
- **B.** C and D are independent because P(C∩D) does not equal P(C)P(D). P(C∩D) = [ ], and P(C)P(D) = [ ].
  
- **C.** C and D are dependent because P(C∩D) equals P(C)P(D). P(C∩D) = [ ], and P(C)P(D) = [ ].
  
- **D.** C and D are independent because P(C∩D) equals P(C)P(D). P(C∩D) = [ ], and P(C)P(D) = [ ].

**Explanation:**

- **P(C∩D):** This represents the probability of both events C and D occurring simultaneously.
- **P(C):** This represents the probability of event C occurring.
- **P(D):** This represents the probability of event D occurring.

To determine if events C and D are independent, fill in the probabilities to check if P(C∩D) equals P(C)P(D). If they are equal, the events are independent. If not, they are dependent.

Expert Solution
Step 1

Solution:

We know that two events C and D are independent if any one of the following conditions hold.

1)P(CD) =P(C)×P(D)2)P(C|D) =P(C)3)P(D|C) =P(D)
