The ohms rating of a television cable is not resistance. It's impedance and is called the characteristic impedance. The impedance of coaxial cable doesn't add like a resistance does. Two 75 ohm impedance cables will combine in parallel to get 50 ohms impedance. While TV cable is normally 75 ohms impedance, another impedance is 50 ohms, typical for 2-way radio. A coaxial cable can be other impedances as well. The exact impedance is important to maximize performance. The impedance is determined by the ratio of the outside conductor to the inside conductor. See the link below for more details.

Ohms are Ohms are Ohms. Doesn't matter the application.

Ohms in series add them together = 50+50 = 100 Ohms.

Ohms in parallel - add the inverse = 25 Ohms.
