Which of the following conditions must be met for a random variable X to have a valid probability distribution? A. The sum of the probabilities in the distribution must be 1. B. There are no conditions required for a valid probability distribution C. The probabilities must all be equal for all possible outcomes. D. The P(X) must be between 0 and 1 for all possible outcomes. E. None of the probabilities can be equal for any possible outcomes.

Step 1
The sum of the probabilities in the distribution must be 1. This is true because in a probability distribution, the probabilities assigned to all possible outcomes must add up to 1. This ensures that the total probability of all possible outcomes is accounted Show more…

Which of the following conditions must be met for a random variable X to have a valid probability distribution? There are no conditions required for a valid probability distribution The probabilities must all be equal for all possible outcomes. None of the probabilities can be equal for any possible outcomes. The P(X) must be between 0 and 1 for all possible outcomes. The sum of the probabilities in the distribution must be 1.

Which of these statements is not a condition of a discrete probability distribution? A. The sum of the probabilities for all the outcomes in the distribution needs to add up to 1. B. Each outcome in the distribution needs to be mutually exclusive with other outcomes in the distribution. C. The probability of a success must exceed the probability of a failure. D. The probability of each outcome, P(x), must be between 0 and 1 (inclusive).

Determine whether or not the following distribution is a probability distribution. If the distribution is not a probability distribution, give the characteristic which is not satisfied by the distribution. P(X=x)=x2−5110 , for x=3,4,5,6,7Multiple Choice a. No, the probabilities are not additive b. No, the sum of the probabilities is not equal to 1 and one or more of the probabilities do not fall between 0 and 1 inclusively. c. No the sum of the probabilities is not equal to 1. d. Yes, the distribution meets all three properties of a discrete probability distribution. e. No, one or more of the probabilities do not fall between 0 and 1 inclusively
