I got 15xy+7y+5x
Use the product and chain rules.
We want dy/dx.
dy/dx = (5x+7)(x+5)^3
dy/dx = (5x+7)3(x+5)^2 + (x+5)^3 (5)
We now simplify as much as possible.
dy/dx = 3(5x+7)(x+5)^2 + 5(x+5)^3

Step-by-step explanation:
The calculations for this lottery <em>do not involve </em>the combinations rule because <em>the order of the numbers does matter</em>. For example, 1234 and 4321 are different although they have the same digits.
The calculations for this lottery <em>do involve</em> the permutations with replacement rule because any selected number can be used more than once.
By <em>the fundamental rule of counting</em>, there are 10*10*10*10 = 10,000 possible outcomes of the event with a probability 1/10,000 = 0.0001 each outcome.
