Answer:
The probability of rolling a doubles or getting two numbers whose sum is equal to 8 is 0.278.
Step-by-step explanation:
There are a total of <em>N</em> = 36 outcomes when rolling two fair dice.
The outcomes for rolling doubles are: {(1, 1), (2, 2), (3, 3), (4, 4), (5, 5), (6, 6)}.
So, n (Doubles) = n (D) = 6
The outcomes for rolling a sum of 8 are: {(2, 6), (3, 5), (4, 4), (5, 3), (6, 2)}
So, n (Sum 8) = n (S8) = 5
Considering the outcomes of the above two events, it can be seen that there is a common outcome, i.e. (4, 4).
So, n (D ∩ S8) = 1
Compute the probability of rolling a doubles or getting two numbers whose sum is equal to 8 as follows:
Thus, the probability of rolling a doubles or getting two numbers whose sum is equal to 8 is 0.278.
Answer:
2 and 12 have same chance of occurring
3 and 11
4 and 10
5 and 9
6 and 8
Each pair has same occurrence chance
Step-by-step explanation:
Here, we are interested in calculating knowing the sums that have an equal chance of occurrence.
Firstly, we need a sample space. A sample space refers to the set of all possible results.
Please check attachment for this
From the sample space we have 36 results;
Let’s list the outcomes and the number of times they all appear;
1- 0
2- 1
3- 2
4-3
5-4
6-5
7- 6
8- 5
9-4
10-3
11- 2
12-1
From the above, we can see that;
2 and 12 have same chance
3 and 11
4 and 10
5 and 9
6 and 8
