Among the following distributions of the random variable $X$, which one does not belong to a binomial distribution?

① According to the CCTV News, the probability of a computer being infected by a certain virus after downloading data from a certain website within the next week is 0.65. Suppose that a computer downloads data from this website $n$ times within this week, and the number of times it gets infected by this virus is $X$; ② A shooter has a probability $p$ of hitting the target with each shot, assuming each shot is independent. The number of shots needed to hit the target for the first time is $X$; ③ A shooter has a probability $p$ of hitting the target with each shot, assuming each shot is independent. The number of times the target is hit after $n$ shots is $X$; ④ Near a certain bus station, there is a gas station, and the probability of a car going to this gas station for refueling after leaving the station is 0.6. On National Day, 50 cars leave the station, assuming that each car's decision to refuel at this gas station is independent throughout the day, and the number of cars that go to this gas station for refueling is $X$.
