2.35. If we 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 impossi- ble that it will be non-representative, such as having only females in the sample.
