I think the answer is C.40
The probability of compound events refers to mathematical formulas and methods that are used to find out the likelihood that two independent events will happen.
<h3>What is compound probability?</h3>
Your question is incomplete so instead, I'll give an overview of compound events probability.
Compound events refer to independent events so when we look for compound event probability, we are trying to find out how possible it is that both these independent events happen.
The simplest method is by multiplying the probabilities of these two events with the product being the compound probability.

We want to minimize s(x, y) = x + y such that xy = 36.
From the constratint we have y = 36/x, so the sum can also be written as
s(x, 36/x) = x + 36/x
Differentiate s with respect to x and find the critical points of s :
1 - 36/x² = 0 ⇒ x² = 36 ⇒ x = ±6
Both x and y must be positive, so it follows that x = y = 6, which gives a minimum sum of s(6, 6) = 12.
Answer:
C. 3/5
Explanation:
Moving 4 to the other side of the equation means we switch the sign for 4. so it is now 7-4 which is 3. if you move 5 to the other side it becomes divide because it was multiplying x-y in the other side. so x-y = 3/5
