Determine whether the distribution is a probability distribution of a discrete random variable. 1. x -2 0 2 4
P (x) 0.3 0.5 02. 01

2. x 0.5 0.25 0.25
P(x) -0.4 0.6 0.8

3. x 1.1 2.5 4.1 4.6 5.3
P(x) 0.16 0.14 0.11 0.27 0.22

20

step-by-step explanation:

question 1 is 8, question 2 is 9, question 3 is 24

step-by-step explanation:

now, the numbers they give you at the top are the key. from there, you just have to plug and chug! let's try 1, 2, and 3!

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24

time to try the rest on your own! if you put the answers below in a comment, i'll check them for you!
