I have a problem with people at my school, they doesnt have any interest in sports and i want to make them have fun when playing basketball but i dont know how.

Make them watch Kuroko

Yeah I agree With the person above me.
KnB really made me to want to play basketbal

holy crap more people like me. kuroko no basuke is what made me start playing basketball. the anime is so amazing. I disliked basketball before watching the anime now its my second favorite sport

Make them play basketball.
Ask the Teachers if they can Organize a basketball tournament or something like that.

This was my school/class until 3 years ago. A few bunch of people who wouldn't get to play as much football started playing bball and it gradually became a thing. It is a great sport, just get the ball rolling.

Make it enjoyable. If your PE teachers makes a whole class of 30 take turns to shoot at the hoop, then it's all too slow paced and no one has fun. Split the class into groups of 5, and have 2 groups at a time playing real matches. Don't focus too much on the rules since for people who don't like basketball, the rules will just be a buzzkill. My school did this and after seeing the sporty group playing, one by one the less sporty people started joining in and eventually the majority of the class was playing. Although you'll never get everyone playing basketball.

Make them watch Kuroko no Basket :D

To me I only liked and got inspired by kuroku no basket. I forced my friends to play it and then as soon as u know it they all liked it.

I would have not like basket if it weren't for KNB

Me and my friends play a lot of pickup games (3 on 3) at the outdoor courts - I would try to get your friends to do this just once! They'll be hooked for sure!
