Answer:
C. A sample of size n from a population of size N is obtained through simple random sampling if every possible sample of size n has an equally likely chance of occurring. The sample is then called a simple random sample.
Step-by-step explanation:
Simple Random Sampling is the sampling where samples are chosen randomly, where each unit has an equal chance of being selected in a sample.
Option A is incorrect as the size of the sample and size of the population is not the same generally if it does happen then there will be no difference between sample and population.
Option B is incorrect as Simple Random Sampling is not a chance it is a way that samples can be taken.
Option D is incorrect as when samples are taken using a convenient sample then it is called Convenient Sample, not Simple Random Sample.
Thus, only option C is correct.

Step-by-step explanation:
Given that Lenox ironed 1/4 of the shirts over the weekend, and she plans to split the remainder of the work equally over the next 5 evenings, to determine what fraction of the shirts will Lenox iron each day after school, and, if lenox has 40 shirts, how many shirts will she need to go on Thursday and Friday, the following calculations must be performed:
1---
(3/4) / 5 = X
0.15 = X
15/100 = X
3/20 = X
So each day she will iron 3/20 of her shirts.
2---
40 x (3/20) x 2 = X
6 x 2 = X
12 = X
So on Thursday and Friday she will iron 12 shirts.
