Answer:
Step-by-step explanation:
Firstly, you need to know that raising a fraction to a power raises both the top and the bottom to that power.
Second, a negative power on the top and bottom flips the fraction
Last, raising a power to a power multiplies the powers
So, 
=
=
=
Answer: 0.79
Step-by-step explanation:
I will suppose that this is not a continuos probability, as the individual probabilites add up to 100%.
If you want to obtain the probability that x ≤ 0, then you need to add the probability for the cases x= 0, x = -1, x = -2 .... etc
This is:
x = 0, p = .16
x = -2, p = .33
x = -3, p = .13
x = -5, p = .17
Then, the probability where x takes a negative value or zero {-5, -3, -2, 0} is:
P = 0.16 + 0.33 + 0.13 + 0.17 = 0.79
I would say c hope this helps
The third one is the correct choice because the solutions are 2 and -2
