The Probability Mass Function (PMF) is also called a probability function or frequency function which characterizes the distribution of a discrete random variable. Determine the value of c such that f(x) represents a probability density function. The deﬁnition of expectation follows our intuition. b) Find the standard deviation. Literals. a statistical expression that defines a probability distribution (the likelihood of an outcome) for a discrete random variable(e.g., The wait time (in minutes) for a table at a busy restaurant on the weekend is distributed according to the density function given above.. A customer plans to dine in this restaurant on two different weekends. In particular, we have the following definition: A continuous random variable X is said to have a Uniform distribution over the interval [ a, b], shown as X ∼ U n i f o r m ( a, b), if its PDF is given by. b Probability of interval [a, b] is given by f (x)dx, the area.

These short objective type questions with answers are very important for Board exams as well as competitive exams. Process control is necessary, but measurement data cannot be obtained. These short solved questions or quizzes are provided by Gkseries. "Density function" itself is also used for the probability mass function, leading to further confusion. In general though, the PMF is used in the context of discrete random variables (random variables that take values on a discrete set), while PDF is used in the context of continuous random variables.
