- Constructing a probability distribution for random variable
A continuous random variable takes on an uncountably infinite number of possible values. We'll do that using a probability density function "p. We'll first motivate a p. Even though a fast-food chain might advertise a hamburger as weighing a quarter-pound, you can well imagine that it is not exactly 0. One randomly selected hamburger might weigh 0.

Associated to each possible value x of a discrete random variable X is the probability P x that X will take the value x in one trial of the experiment. The probability distribution A list of each possible value and its probability. The probabilities in the probability distribution of a random variable X must satisfy the following two conditions:. A fair coin is tossed twice. Let X be the number of heads that are observed.
There are two types of random variables , discrete random variables and continuous random variables. The values of a discrete random variable are countable, which means the values are obtained by counting. All random variables we discussed in previous examples are discrete random variables. We counted the number of red balls, the number of heads, or the number of female children to get the corresponding random variable values. The values of a continuous random variable are uncountable, which means the values are not obtained by counting.
examine two of the most important examples of discrete random variables: the of a discrete random variable and the associated probability distributions. Solution. The possible permutations are. ABCD ABDC ADBC ADCB ACBD ACDB.
