Math Problem Statement

Six different colored dice are rolled. Of interest is the number of dice that show a "5." Find the probability that all six dice show a "5." (Round your answer to five decimal places.)

Solution

To calculate the probability that all six dice show a "5," we need to understand that:

  • A standard die has 6 faces, and the probability of rolling a "5" on a single die is 16\frac{1}{6}.
  • Since the dice rolls are independent, the probability that all six dice show a "5" is the product of the probabilities for each individual die.

Thus, the probability is:

P(all six dice show a "5")=(16)6P(\text{all six dice show a "5"}) = \left(\frac{1}{6}\right)^6

Let's compute this:

P(all six dice show a "5")=(16)6=1466560.00002143P(\text{all six dice show a "5"}) = \left(\frac{1}{6}\right)^6 = \frac{1}{46656} \approx 0.00002143

So, the probability that all six dice show a "5" is approximately 0.00002 (rounded to five decimal places).

Here are some related questions you might find interesting:

  1. What is the probability that exactly one die shows a "5"?
  2. What is the probability that at least one die shows a "5"?
  3. How do you calculate the probability of a specific outcome with multiple dice rolls?
  4. If 10 dice are rolled, how would you calculate the probability that all show a "5"?
  5. How can you apply this method to other probability problems involving dice?

Tip: When calculating probabilities with multiple independent events (like dice rolls), you multiply the probabilities of the individual events together.
