Two fair dice are rolled. find the probability of a "double" given that the sum is 11.
Sergio [31]
Star with the statement: "Given that the sum is 11"
which may seem a bit odd considering its the last part of the problem

The "given" is important as it sets up the constraints of what we're dealing with. In this case, we know 100% (we can see or someone told us without lying) that the sum is 11. We don't know what the individual values are but we know they add to 11.

What are the ways to add to 11? Well they are...
5+6 = 11
6+5 = 11
so there are 2 ways to do it. As you can see, none of those ways involve a double. A double is where we have two of the same values (eg: snake eyes which is 1 and 1 giving 1+1 = 2 as the sum). It turns out that it's impossible to have doubles add to any odd number.

So if we know the sum is 11, and we're asking "what is the probability of rolling doubles", then the answer is 0. 
The 0 indicates "impossible" or "certainty of it never happening".

Your realized income is $2,943.20 /month. How much are your fixed expenses each month? How much could you save per month if you
valkas [14]

Answer:

The saving amount per month is $ 735.8 And

The Expenses amount per month is $2,207.4

Step-by-step explanation:

Given as :

The total per month income = $2,943.20

The saving percentage amount per month = 25% of discretionary money  

So , The saving amount per month = 25 % of $2,943.20

                                                          = .25 × $2,943.20 = $735.8

The amount which is fixed as each month expenses = total monthly income - total monthly saving

So, Expenses amount per month = $2,943.20 - $735.8

                                                       = $2,207.4

Hence The saving amount per month is $ 735.8 And The Expenses amount per month is $2,207.4     Answer
