two 6 sided dice are rolled.what is the probability the sum of the 2 numbers on the dice will be 4
Is 1/3 right?
How do you get a 4 ?
1,3 3,1 2,2
that is 3 ways,
so prob = 3/36
= 1/12
i got 1/9
How can you get 1/9 ?
Didn't I show you that there only 3 ways to get a sum of 4?
1,3
3,1 and
2,2
so the prob is 3/36 = 1/12
as I showed you.
To find the probability of rolling a sum of 4 with two 6-sided dice, we need to determine the number of favorable outcomes (rolling a sum of 4) and the total number of possible outcomes.
First, let's identify the favorable outcomes:
To roll a sum of 4, we can have the following combinations:
- 1 on the first die and 3 on the second die
- 2 on the first die and 2 on the second die
- 3 on the first die and 1 on the second die
So, there are 3 favorable outcomes.
Next, let's determine the total number of possible outcomes:
Since we have two 6-sided dice, each die can land on any number between 1 and 6. Therefore, the total number of possible outcomes is calculated by multiplying the number of possible outcomes for each die. In this case, it is 6 * 6 = 36.
Finally, we can calculate the probability by dividing the number of favorable outcomes by the total number of possible outcomes:
Probability = Favorable Outcomes / Total Possible Outcomes = 3 / 36 = 1 / 12
Therefore, the correct probability of rolling a sum of 4 with two 6-sided dice is 1/12, not 1/3.
