Using the randomly selected male and female students, suppose that the probability of a male student living in his parents' house is 0.55, and the probability of a female student living in her parents' house is 0.34. In addition, suppose that the probability of both male and female students living in their parents' house is 0.15.

What is the probability both male and female students selected is living outside of their parents' house ( so neither living with their parents)?
