Oct 13, 2025 by wbrum.org 110 views

Introduction

When two dice are rolled together, there are various possible outcomes. In this article, we will explore the probability of getting specific outcomes, such as a multiple of 2 on one die and a multiple of 3 on the other die, and the product of two numbers on the top of the two dice being a perfect square number.

Probability of Getting a Multiple of 2 on One Die and a Multiple of 3 on the Other Die

To find the probability of getting a multiple of 2 on one die and a multiple of 3 on the other die, we need to consider the possible outcomes of each die.

Possible Outcomes of Each Die

Each die has 6 possible outcomes: 1, 2, 3, 4, 5, and 6.

Multiples of 2 on One Die

The multiples of 2 on one die are 2, 4, and 6.

Multiples of 3 on the Other Die

The multiples of 3 on the other die are 3 and 6.

Total Number of Favorable Outcomes

The total number of favorable outcomes is the product of the number of multiples of 2 on one die and the number of multiples of 3 on the other die, which is 3 x 2 = 6.

Total Number of Possible Outcomes

The total number of possible outcomes is the product of the number of possible outcomes of each die, which is 6 x 6 = 36.

Probability of Getting a Multiple of 2 on One Die and a Multiple of 3 on the Other Die

The probability of getting a multiple of 2 on one die and a multiple of 3 on the other die is the ratio of the total number of favorable outcomes to the total number of possible outcomes, which is 6/36 = 1/6.

Probability of Getting the Product of Two Numbers on the Top of the Two Dice as a Perfect Square Number

To find the probability of getting the product of two numbers on the top of the two dice as a perfect square number, we need to consider the possible outcomes of each die.

Possible Outcomes of Each Die

Each die has 6 possible outcomes: 1, 2, 3, 4, 5, and 6.

Perfect Square Numbers

The perfect square numbers that can be obtained by multiplying the numbers on the top of the two dice are 1, 4, and 9.

Total Number of Favorable Outcomes

The total number of favorable outcomes is the number of perfect square numbers that can be obtained by multiplying the numbers on the top of the two dice, which is 3.

Total Number of Possible Outcomes

The total number of possible outcomes is the product of the number of possible outcomes of each die, which is 6 x 6 = 36.

Probability of Getting the Product of Two Numbers on the Top of the Two Dice as a Perfect Square Number

The probability of getting the product of two numbers on the top of the two dice as a perfect square number is the ratio of the total number of favorable outcomes to the total number of possible outcomes, which is 3/36 = 1/12.

Conclusion

In this article, we have explored the probability of getting specific outcomes when two dice are rolled together. We have found that the probability of getting a multiple of 2 on one die and a multiple of 3 on the other die is 1/6, and the probability of getting the product of two numbers on the top of the two dice as a perfect square number is 1/12.
