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.
1: m=-4
2: b=-4
3: -9=k
4: C=-11.4
5:X<10
