The valid probability distributions are the ones in options C and D.
<h3>
Which of the following are valid probability distributions?</h3>
For discrete random variables with probabilities p₁, p₂, ..., pₙ, there are two rules:
- All of these probabilities are numbers between 0 and 1.
- p₁ + p₂ + ... + pₙ = 1.
So, for the first rule we can discard the first option, where we have negative probabilities.
To check the other 4 options, just add the probabilities and see if the addition gives 1.
The options that add up to 1 are C and D, so these two are the correct options.
D: 1/5 + 1/10 + 1/10 + 1/10 + 1/5 + 1/10 + 1/10 + 1/10 = 1
C: 1/6 + 1/6 + 1/6 + 1/6 + 1/6 + 1/6 = 1

Answer:5,5
Step-by-step explanation:
Answer:
m= -1/2
Step-by-step explanation:
Parallel lines have the same slope, so find the slope between the 2 points.
0 - ( -1 ) / -6 - ( -4) = 1/-2
The slope (m) is -4 , and the y-intercept (b) is 8. Slope intercept form is y = mx+b
Y=-4x+8
