The probability of $2$ elephants in the city zoo having the same weight is between $0$ and $0.5$.

Work Step by Step

While it is theoretically possible that two elephants have the same weight, it is unlikely. Elephants weigh a lot and there probably aren't that many of them in the zoo, so even two that are roughly the same size could differ in weight by as much as 100 pounds. Therefore, we assign a low but nonzero probability to the event that two elephants have the same weight.
