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:
N=6-2
Step-by-step explanation:
When speaking the language of math, "the same as" just means equal to. On the left side of the equal sign, you have your variable, and on the right is the rest of the equation. 6 reduced by 2 is the same thing as 6-2
Answer:
This is an independent event, as the marble is put back into the bag. If it were removed completely, it would be dependent.
