Using probability concepts, it is found that:
a) The missing value is 0.04.
b) The mean is of 0.37.
The distribution is given by:




Item a:
The sum of <u>all the probabilities has to be 1</u>, that is:

Thus:



The missing value is 0.04.
Item b:
The mean is given by the <u>sum of each outcome multiplied by it's probability</u>, thus:

The mean is of 0.37.

Answer:
Step-by-step explanation:
There isn't one. The first term is x^4.
The other two are stated in terms of k. There is nothing common here.
You can do 2 of the three. Terms 2 and 3 have a common factor of 4k, so what you can get is
x^4 - 4k(k^2 - 1)

Here’s why:
- A trinomial is a expression that consists of three terms.
- A term can be a number, variable, or both numbers and variables that are multiplied together.
- Answer choice 'D' has three terms, c², 'c', and '6'. Therefore, it is a trinomial.
