Examine the following table. x
1
2
3
4
5
P(x)
0.2
0.3
0.4
0.1
0.05

Does this table represent a probability distribution? Explain your answer.
a.
Yes, because the sum of the probabilites is less than one.

Yes, because the sum of the probabilities is more than one.
c.

d.
No, because the sum of the probabilities is less than one.

there is no picture

step-by-step explanation:

put up a picture so people can you

- 2 + 10x³ - 21x² + 19x - 4

step-by-step explanation:

each term in the second factor is multiplied by each term in the first factor

x²(- 2x² + 4x - 1) - 3x(- 2x² + 4x - 1) + 4(- 2x² + 4x - 1) ← distribute

= - 2 + 4x³ - x² + 6x³ - 12x² + 3x -8x² + 16x - 4

collect like terms

= - 2 + 10x³ - 21x² + 19x - 4 ← in standard form

g(x) is the negative form of f(x)? because whenever its the negative form it reflects its self over the x axis. idk if this is right though.
