Problem 147 of 7
Compute probability of unordered compound event using multiple paths: at least one four in two rolls of a fair die.
Using a hint is okay. It just tells the trainer to give you a little more review.
Hidden until you reveal it.
combine multiplication and addition across paths.
Hidden until you reveal it.
Add probabilities of distinct valid paths or use complement where appropriate.
Enter your answer
Your answer is equivalent to the expected form.
Walkthrough
Full solution stays hidden until you ask for it.
1. Identify all ordered paths that satisfy the unordered event.
2. Compute each path probability by multiplication.
3. Add disjoint path probabilities or use complement.
Use the worked steps, then substitute the final answer back into the original relationship to confirm it satisfies the prompt.
Giving only one order when multiple orders satisfy the event.
