Verizon Internet and Comcast Cable TV

I'm moving into a new place soon with another person, and they already have Comcast cable tv set up there. I was wondering if it's possible for me to have Verizon FiOS Internet set up there and for them to keep their Comcast TV while living in the same house?

They only watch TV, and I only use the internet but they like comcast and I like verizon which is why I'm asking if this is possible, thanks in advance.
