Question

Please check my answer:

Consider the students in your statistics class as the population
and suppose they are seated in four rows of 10 students each. To select a
sample, you toss a coin. If it comes up heads, you use the 20 students sitting in
the first two rows as your sample. If it comes up tails, you use the 20 students sitting
in the last two rows as your sample.
Does every student have an equal chance of being selected for the sample?
