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
Answer:
There is NO solution
Step-by-step explanation:
Considering 'y' be the number
Considering x be the smaller number
As 'y' is equal to twice a smaller number plus 3.
so
also
y is equal to twice the sum of the smaller number and 1.
so
so the system of equations become
solving
Therefore, there is NO solution.
