This count is a discrete random variable (option A).
<h3>What is a
discrete random variable?</h3>
A discrete random variable is a variable that contains integers that can only be a limited number of possible values. A discrete random variable is can contain only a finite set of numbers .
An example of discrete random variable is the number of students in the first period class. It is impossible for the number of students in the class to go on indefinitely.
Discrete random variable has the following properties:
- It is finite
- It is numeric
- It is countable
- It contains non-negative integers.
A continous random variable is a variable that has an infinite number.

Answer:
15x = y
Step-by-step explanation:
15 times the gallons of gas = miles
15x = y
The next step is to solve the recurrence, but let's back up a bit. You should have found that the ODE in terms of the power series expansion for


which indeed gives the recurrence you found,

but in order to get anywhere with this, you need at least three initial conditions. The constant term tells you that

, and substituting this into the recurrence, you find that

for all

.
Next, the linear term tells you that

, or

.
Now, if

is the first term in the sequence, then by the recurrence you have



and so on, such that

for all

.
Finally, the quadratic term gives

, or

. Then by the recurrence,




and so on, such that

for all

.
Now, the solution was proposed to be

so the general solution would be


Answer:
n[total]=25
n[top finishers]=8
the number of possible outcome
=
