I would like to know if my answer is correct
Question: If a random sample of size n = 3 is drawn from a finite population of size N = 50, what is the probability that a particular element of the population will be included in the sample?
Answer: ((49C2) x 3) / (50C3) = 0.18 = 18% I calculated the number of possible groups of 2 of 49 people and then multiplied by 3 because you can have the wanted person in every of the 3 positions and then divided by all the possible groups of 50 people taken by 3
