Answer:

A discrete probability distribution is a probability distribution where the random variable takes on a finite number of distinct values.

Looking at the options provided:

A. X 3 4 5

P(X) 0.40 0.10 0.5

B. X 1 2 3 4

P(X) 1/5 3/10 1/5 3/10

C. X 1 2 3 4

P(X) 0.15 0.35 0.40 0.5

D. X 0 2 4 6

P(X) 1/5 1/5 2/5 1/5

Out of the given options, option A and option C are discrete probability distributions because the random variable X takes on a finite number of distinct values.

Option B is not a discrete probability distribution because the probabilities do not add up to 1.

Option D is also not a discrete probability distribution because the probabilities assigned to the values do not sum up to 1.

Therefore, the correct answer is:

A. X 3 4 5

P(X) 0.40 0.10 0.5

C. X 1 2 3 4

P(X) 0.15 0.35 0.40 0.5

Step-by-step explanation:

A discrete probability distribution is a probability distribution where the random variable takes on a finite number of distinct values.

Looking at the options provided:

A. X 3 4 5

P(X) 0.40 0.10 0.5

B. X 1 2 3 4

P(X) 1/5 3/10 1/5 3/10

C. X 1 2 3 4

P(X) 0.15 0.35 0.40 0.5

D. X 0 2 4 6

P(X) 1/5 1/5 2/5 1/5

Out of the given options, option A and option C are discrete probability distributions because the random variable X takes on a finite number of distinct values.

Option B is not a discrete probability distribution because the probabilities do not add up to 1.

Option D is also not a discrete probability distribution because the probabilities assigned to the values do not sum up to 1.

Therefore, the correct answer is:

A. X 3 4 5

P(X) 0.40 0.10 0.5

C. X 1 2 3 4

P(X) 0.15 0.35 0.40 0.5
