Explanation: 

Detailed explanation-1: -Systematic sampling is a type of probability sampling method in which sample members from a larger population are selected according to a random starting point but with a fixed, periodic interval. This interval, called the sampling interval, is calculated by dividing the population size by the desired sample size.

Detailed explanation-2: -Probability sampling requires that each member of the survey population has a known probability of being included in the sample, but it does not require that this probability be the same for everyone.

Detailed explanation-3: -How do we draw a 1 in k systematic sample? Example: Suppose our population is 9, 000 students and we want to sample 1, 200 students. How do we sample these students systematically? Since, 9000/1200 = 7.5, we can perform a 1-in-7 systematic sample.
