It is not a <u>probability distribution</u>, as the sum of the probabilities is more than 1, thus, the correct option is No, considering that:
c) Since the sum of the probabilities is not equal to 1.
-----------------------------------------
For the sequence 
representing a probability distribution, it is needed that:
- All probabilities are between 0 and 1, that is, for all values of x,
. - The sum of all probabilities is 1, that is:
In this problem, the sum of the probabilities is:
<u>Sum is not 1,</u> thus it is not a probability distribution, and the correct option is:
c) Since the sum of the probabilities is not equal to 1.

Answer:
x= -2
Step-by-step explanation:
-1/3(9x-27)=15
Multiplying both sides by -3
9x-27=15×(-3)
9x-27=-45
Now
Add 27 to both sides
9x=-45+27
9x=-18
Divide both sides by 9
x= -2
For a binomial expansion with exponent 5, the general equation is as follows
(x + y)⁵ = x⁵ + 5x⁴y + 10x³y² + 10x²y³ + 5xy⁴ + y⁵
when expanded from left to right the powers of x decrease from 5 to 0 and powers of y increase from 0 to 5
substitute x =2x and y = 5
(2x + 5)⁵ = (2x)⁵ + 5(2x)⁴5 + 10(2x)³5² + 10(2x)²5³ + 5(2x)5⁴ + 5⁵
<span>= 32x⁵ + 400x⁴ + 2000x³ + 5000x² + 6250x + 3125
</span>we use the pascals triangle to find the coefficient
we can use the binomial theorem to find the 4th term as well
exponent - 5
term - 4
5!/ (5-4)!4! * (2x)⁴5⁵⁻⁴
=120/24 *16x⁴*5
=400x⁴
Answer:
apply the BODMAS concept
brackets, off, division, multiplication, addition, subtraction
