Problem 49 of 7
Determine independence from Venn diagram data total 20; A only 6, overlap 4, B only 4, outside 6.
Using a hint is okay. It just tells the trainer to give you a little more review.

Use Venn regions to compute marginal and joint probabilities.
Enter your answer
Your answer is equivalent to the expected form.
Walkthrough
Full solution stays hidden until you ask for it.
1. Compute A total, B total, and overlap from the Venn regions.
2. Convert counts to probabilities.
3. Compare overlap probability to product of marginal probabilities.
Use the worked steps, then substitute the final answer back into the original relationship to confirm it satisfies the prompt.
Treating A only or B only as the joint probability.
