Choose the correct answer below O A. A discrete probability distribution exclusively lists probabilities O B. A discrete probability distribution lists each possible value a random variable can assume. ° C. A discrete probability distribution lists each possible value a random variable can assume. together with its probability. ( D. None of the above What are the two conditions that determine a probability distribution? Choose the correct answer below A. The probability of each value of the discrete random variable is between 0 and 1, inclusive, O B. The probability of each value of the discrete random variable is between 0 and 1, inclusive. ° C. The probability of each value of the discrete random variable is greater than 0 and less than 0 D. The probability of each value of the discrete random variable is greater than 0 and less than and the sum of all the probabilities is 1. and the sum of all the probabilities can be any amount. 1, and the sum of all the probabilities is 1. 1, and the sum of all the probabilities can be any amount.
Explanation / Answer
A discrete probability distribution is the one where there are only some discrete set of values which the random variable can take and not on a continuous range. Each of the discrete value of that random variable has a probability of occurence.
Therefore C is the correct answer here.
The 2 conditions for a discrete probability distribution to be a valid distribution are that the sum of all probabilities should be equal to 1 and each of the probability value must lie between 0 and 1 only.
Therefore A is the correct answer here.
