2.35. Ifwe use random numbers to take a simple random sample of 50 students from the 20,000 students at a university,

(a) It is impossible to get the random number 11111, because it is not a random sequence.

(b) If we get 20001 for the first random number, for the second random number that number is less likely to occur than the other possible five-digit random numbers.

(c) The draw 12345 is no more or less likely than the draw 11111.

(d) Since the sample is random, it is impossible that it will be non-representative, such as having only females in the sample.
