Solution:&amp;nbsp;Discrete distribution is a probability distribution where sample space is countable. The random variable in such a case can only take point values. Example: number of people, or number of coins etc.&amp;nbsp;The two conditions are&amp;nbsp;1) Sum of all probabilities should be equal to 1&amp;nbsp;2) Each probability must be&amp;nbsp;≥0

A discrete pdf is a pdf of a discrete variable like the number of eyes thrown by a dice.&amp;nbsp;The sum of all probabilities is 1 and the probabilities are&amp;nbsp;≥0.&amp;nbsp;Solution:&amp;nbsp;A discrete variable has a finite number of distinct values.&amp;nbsp;similar to dice&#039;s tossed eyes: 1,2,3,4,5, or 6.&amp;nbsp;The discrete pdf for a dice throw is:&amp;nbsp;P[X=k]=1/6, k=1,2,...,5,6.&amp;nbsp;The pdf for the amount of rainfall in a month e.g. is not discrete since the values are continuous and there is no upper bound.
