Question
The exam will consist of a 10-character sequence which students will have to write in stats class. They will have a machine select each character of the sequence independently and uniformly at random from {a, b, . . . , z}∪{A, B, . . . , Z}∪{0, 1, . . . , 9} right before the exam:
(1) What is the
(2) What is the expected number of digits in a sequence?
(3) What is the variance of the number of digits in a sequence?
