Probability that a randomly selected freshman student owns a computer = 51.4% = 0.514
P(selecting a random student who does not own a computer)
= 1 - P(selecting a random student who owns a computer)
= 1 - 0.514
= 0.486
= 48.6%
The event of selecting a freshman who does not own a computer is called the complement event.
[
Reason:
In probability theory, the complement of any event A is the event "not A" i.e. the event that A does not occur.
Here let,
A be the event that the freshman has a computer. Hence, complement of A or Ac is the event that the freshman does not have a computer.

The Higher Education Research Institute at UCLA collected data from 203,967 incoming first-time, full-time freshmen from 270 four-year colleges and universities in the U.S. 71.3% of those students replied that, yes, they believe that same-sex couples should have the right to legal marital status. Suppose that you randomly select freshman from the study until you find one who replies "yes." You are interested in the number of freshmen you must ask. What is the probability that you will need to...
