Answer:
The probability that a customer purchases a black SUV is 0.05.
Step-by-step explanation:
<em>The question is incomplete:</em>
<em>At a certain car dealership, the probability that a customer purchases an SUV is </em><em>0.20</em><em>. Given that a customer purchases an SUV, the probability that it is black is </em><em>0.25</em><em>.</em>
The probability that a customer purchases a black SUV can be calculated as the multiplication of this 2 factors:
- The probability of a customer purchasing a SUV: P(SUV).
- The probability that it is black, given that he or she purchases a SUV (conditional probabilty): P(B|SUV)
We know then:
We can now calculate the probability as:
Answer:
I would say A because 6:3 can only equal 1/3.

It would help if you formatted a bit better though. As the choices are not clear. ^^
Answer:
x² - (4 ≤ 5)
Step-by-step explanation:
(I have x representing the number that is squared, it might be a different letter on your options, but regardless it will be the same general answer. You also may not need the parentheses around the 4 ≤ 5)
Difference means subtraction so we know that the second number/group of numbers will be subtracted from the first that is listed.
Next, if you are squaring any number it's going to have the little 2 to the right of it. That's what that means.
Then, we look at that last bit. <em>"Four is less than or equal to five."</em> This means exactly how it sounds. To write this we need the symbol ≤. This symbol means less than or equal to. You would would but the 4 in front and the 5 in back to get 4 ≤ 5.
Now we just put it together. It tells us that 4 ≤ 5 is being subtracted from a number squared. So this means that a number squared needs to be first, and because difference means subtraction, we would subtract 4 ≤ 5 from that. A number squared can be represented by any letter variable, but for this example, I will use x.
This leaves you with x² - (4 ≤ 5)
I hope this helped :)
