Basement Rough-In

[leannel]

I'm going to try to install a bathroom, laundry room, and a kitchen ett in my
unfinished basement. My question is at one end there are three pipes sticking
out of the concrete, one is 3" and the other two are 2" all fairly close to each other. Then in aprox. the middle of the basement there are 2 set's of 2" pipes coming up through the cement floor 4 pipes altogether, and about four feet away from each other. What are they? More vent or drain pipes? Can a 2" pipe be used for a toilet? I thought 3" someone said you could use 2", is that true ? Any help would be greatly appreciated. Thanks for your time.

Are the ends of the pipes open or are the capped off??

One of the group of four is capped offed. And at the other end one of the three is capped offed.
