Question

Can someone help me with this I figured out a similar problem P(x) = xsquare+5 over 50 for x = 1 got 0.12 But having problems on how to plug the numbers into this problem. you don't have to use these numbers but if someone could do an example for me I would appreciate it.
Test the following function to determine whether it is a probability function. If it is not, then make it into a probability function. (Give your answers correct to one decimal place.)
R(x) = 0.2, for x = 0, 1, 2, 3, 4

(a) List the distribution of probabilities.
R(0) =
R(1) =
R(2) =
R(3) =
R(4) =

Answer 1

This is a discrete probability function which has the following characteristics:
1. The function is non-negative throughout its domain.
2. ΣR(i)=1 for i∈ domain
From the given data,
R(0)=0.2
R(1)=0.2
...
R(4)=0.2
for a sum of 1.0.

Answer 2

Thank you I was making it harder than it is.

Answer 3

You're welcome!
