Each outcome in a discrete probability distribution must be 0 or 1. True false False true Single A discrete probability distribution is also called probability mass function. True true False false Single When rolling a fair die, the probability of rolling an even number is greater than the probability of rolling a number less than or equal to 3. True false False true Single The vertical axis of a probability histogram represents the values of the random variable. True false False true Single A continuous variable is a variable that can assume an infinite number of values between an interval. True true False false Single The probabilities in a probability histogram sum up to 1 or approximately equal to 1. True true False false Single The probabilities of the values of a random variable X are 1/3, 1/4 and 1/6 respectively. This is an example of a discrete probability distribution. True false False true Single Answering a multiple choice question follows a discrete probability distribution. True true False false Single Variables can either be discrete or continuous.
