4. Suppose there were 10,000 students at this university and we took a random sample of 100 of them drawn from a “frame” provided by the Registrar’s office. Because of the method we used, we knew the probability of a member of the population to be selected into our sample was 100/10000=.01 or 1%. Which of the following best describes the sampling method we use?

   	a.	simple random sampling
   	b.	cluster sampling
   	c.	convenience sampling
   	d.	probability sampling
