The expression is equivalent to r^(m-n)
Using Venn probabilities, it is found that P(F) = -0.07, which is not a probability, as it is a negative value.
------------------
- We have two events, E and F.
- Their probabilities are:

- The probabilities are related by the following equation:

- Replacing into the equation, we can find P(F).



P(F) = -0.07, which is not a probability, as it is a negative value.

<span>Three numbers can be defined as x, y, and z.
x + y + z = 64
y = x+3
z = 2x - 11
.
substitute for y and z
x + (x+3) + (2x-11) = 64
4x -8 = 64
4x = 72
x = 18
.
y = x+3 = 21
z = 2x -11 = 2(18) -11 = 36-11 = 25
.
x + y + z = 18 + 21 + 25 = 64
Correct.
.
Answer: The three numbers are 18, 21, and 25.</span>
