What happens if someone has to afk or leave in a middle of a raid?

[Tunabros]

I plan to do raiding someday because I never did raiding on p99 but did a bit on live servers. I had a lot of time back then since I was just a student (still in high school).
Now I am a bit older and have a job so I don't have the time to play as much as I did when I was younger.

How long are raids usually? I usually play on weekends each up to 4-5 hours. I do not play on the weekdays because I am too busy with other things in life. Currently I am leveling a cleric, druid, and rogue. I hope to get them to lv 46 soon so I can start raiding. I don't really have much experience with raiding though. So i'm not sure people would like a person in their raid who isn't experienced.

Thanks all!
