Among the following random variable $X$'s distribution, which does not belong to a binomial distribution is __________.  
1. According to a report by 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 the number of times a computer is infected by this virus after downloading data from the website $n$ times within this week is $X$;  
2. The probability of a shooter hitting the target is $p$. Suppose each shot is independent, and the number of shots needed to hit the target for the first time is $X$;  
3. The probability of a shooter hitting the target is $p$. Suppose each shot is independent, and the number of times the target is hit after $n$ shots is $X$;  
4. Near a certain bus station, there is a gas station. 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 the cars going to this gas station for refueling within a day are independent, the number of cars going to the gas station for refueling is $X$.
