The binomial distribution could be used to describe the spread of tennis balls when the players are serving.

The binomial distribution is used for discrete random variables, typically representing the number of successes in a fixed number of independent Bernoulli trials, where each trial has only two possible outcomes (success or failure). The spread of tennis balls when players are serving involves continuous outcomes (the locations where the balls land), which would be better described by a continuous probability distribution, not a binomial distribution.
