Answer:
Step-by-step explanation:
We are given the following in the question:
x: −4 −3 −2 −1 0
P(X=x): 0.2 0.3 0.1 0.2 0.2
We have to evaluate
Since it is a discrete probability distribution as
We can evaluate the probability as:
Thus, 0.4 is the require probability.
That would be 2 because you can divide both by 2 and get a whole number hope this helps
