Question

A mixture of gases at a total pressure of 95 kPa contains N2, CO2, and O2. The partial pressure of the CO2 is 24 kPa and the partial pressure of the N2 is 48 kPa. What is the partial pressure of the O2?

Isn't the sum of the partial pressures equal to the total pressure?
I have no idea how to do these questions. So i don't know.
