1. Mehrin has gone shopping and she got so hyper with excitement that she left
her ATM card in the bank’s ATM machine. A thief got hold of the ATM card.
The card has a four-digit personal identification number (PIN). The thief
knows that the first two digits are 3 and 5, but he does not know the last two
digits. Thus, the PIN could be any number from 3500 to 3599. To protect the
customer, the automatic teller machine will not allow more than three
unsuccessful attempts to enter the PIN. After the third wrong PIN, the machine
keeps the card and allows no further attempts:
a. What is the probability that the thief will find the correct PIN within three
tries? (Assume that the thief will not try the same wrong PIN twice.)
b. If the thief knew that the first two digits were 3 and 5 and that the third digit
was either 1 or 7, what is the probability of the thief guessing the correct PIN
in three attempts?
