Consider a random number generator designed for equally likely outcomes. Which of the following is not correct, and why?
a. For each random digit generated, each integer between 0 and 9 has probability 0.10 of being selected.
b. If you generate 10 random digits, each integer between 0 and 9 must occur exactly once.
c. If you generated a very large number of random digits, then each integer between 0 and 9 would occur close to 10% of the time.
d. The cumulative proportion of times that a 0 is generated tends to get closer to 0.10 as the number of random digits generated gets larger and larger.
