The amount of rain tomorrow

The sum of the probabilities of all outcomes for a discrete random variable must be:

greater than 1

What does the acronym PMF stand for?

Probability Mean Function

Probability Mass Factor

Probability Mass Function

Which of the following is not a discrete random variable?

The probability of an outcome that cannot occur is:

0.5

Which of the following is true about probabilities in a discrete random variable?

Probabilities must all be greater than 0.5

Probabilities cannot be negative

Which of the following is a property of a probability distribution?

Probabilities can be negative as long as the sum is 1

Probabilities are always between 0 and 1

Probabilities must all be equal
