WebbProportional sampling is the method of picking an element proportional to its weight, i.e., the higher the weight of the object, the better are its chances of being selected. In reference to the previously stated dice example, the bigger numbers like five or six will have a higher chance to be selected, rather than a smaller number like one or two.
