Let’s simulate the rolling of a die 20 times and record the results.

Here’s an example of the rolls:

Rolls: 3, 5, 6, 1, 2, 4, 6, 2, 3, 6, 4, 5, 1, 5, 3, 2, 6, 4, 5, 1

Now, based on these rolls, we can tally each outcome:

  • Number of 1s: 3
  • Number of 2s: 3
  • Number of 3s: 3
  • Number of 4s: 3
  • Number of 5s: 5
  • Number of 6s: 5

Let's calculate the probabilities:

  1. Probability of rolling a 6:
    Probability = (Number of 6s) / (Total Rolls) = 5 / 20 = 0.25 (or 25%)

  2. Probability of rolling a 5:
    Probability = (Number of 5s) / (Total Rolls) = 5 / 20 = 0.25 (or 25%)

  3. Probability of rolling a 4:
    Probability = (Number of 4s) / (Total Rolls) = 3 / 20 = 0.15 (or 15%)

  4. Probability of rolling a 3:
    Probability = (Number of 3s) / (Total Rolls) = 3 / 20 = 0.15 (or 15%)

  5. Probability of rolling a 2:
    Probability = (Number of 2s) / (Total Rolls) = 3 / 20 = 0.15 (or 15%)

  6. Probability of rolling a 1:
    Probability = (Number of 1s) / (Total Rolls) = 3 / 20 = 0.15 (or 15%)

Summary of Findings:

  • Probability of rolling a 6: 25%
  • Probability of rolling a 5: 25%
  • Probability of rolling a 4: 15%
  • Probability of rolling a 3: 15%
  • Probability of rolling a 2: 15%
  • Probability of rolling a 1: 15%

Two Dice Scenario:

If you roll two dice instead of one, the probability of rolling at least one “6” increases. There are a few reasons for this:

  1. Increased Outcomes: When rolling two dice, each die can independently land on any of the six sides. More combinations mean a greater likelihood of achieving at least one “6”.

  2. Calculating Probability: The simplest way to think about it is to consider the complementary event (not rolling a 6). The probability of not rolling a 6 on one die is 5/6, so the probability of not rolling a 6 on either of the two dice is (5/6) * (5/6) = 25/36. Therefore, the probability of rolling at least one "6" with two dice is 1 - 25/36 = 11/36, which is approximately 0.305 (or about 30.5%).

Thus, using two dice gives you better odds of rolling a 6 compared to a single die.
