The mean of the discrete distribution that models this situation is of 2.98.
<h3>What is the mean of a discrete distribution?</h3>
The expected value of a discrete distribution is given by the <u>sum of each outcome multiplied by it's respective probability</u>.
Considering the table, the probability distribution is given by:
Hence the mean is given by:
E(X) = 4 x 0.4 + 3 x 0.32 + 2 x 0.17 + 1 x 0.08 + 0 x 0.03 = 2.98.

Answer: (x + 3)(x - 4)
Step-by-Step Solution:
We need to Factorize the given Quadratic Polynomial by using Splitting the Middle Term Method.
= x^2 - x - 12
= x^2 - 4x + 3x - 12
= x(x - 4) + 3(x - 4)
=> (x + 3)(x - 4)
It is A and D because as you can see it is using subtraction and multiplication and I’m sorry if I am wrong I can’t see much
