Answer 2

Calculating the Probability of Rolling No More Than 3 Points on a Six-Sided Die

To calculate the probability of rolling no more than 3 points on a six-sided die, we need to determine the number of favorable outcomes (rolling 1, 2, or 3) and the total number of possible outcomes (rolling any number from 1 to 6).

According to the search results, a standard six-sided die has the numbers 1, 2, 3, 4, 5, and 6 on its faces The favorable outcomes in this case are rolling 1, 2, or 3, which means there are 3 favorable outcomes.

The total number of possible outcomes is 6 since there are 6 faces on the die.

To calculate the probability, we divide the number of favorable outcomes by the total number of possible outcomes:

Probability = Number of Favorable Outcomes / Total Number of Possible Outcomes

Therefore, the probability of rolling no more than 3 points on a six-sided die is:

Probability = 3 / 6 = 1/2 = 0.5

So, the probability is 0.5 or 50%.

Please note that this calculation assumes a fair six-sided die, where each face has an equal chance of landing face-up.

Conclusion

The probability of rolling no more than 3 points on a six-sided die is 0.5 or 50%.
