Quizplus · Accepted Answer

The geometric distribution models the number of independent Bernoulli trials until the first success (in this case, the delivery of twins). Each birth in the hospital can be considered a Bernoulli trial, where the probability of success (delivery of twins) remains fixed and constant (assuming the probability of having twins remains constant throughout the time period analyzed). Therefore, the number of births until the first twins are born follows a geometric distribution.
