"Work dis question out"? Is that at the end of the problem, or your plea to the forum?
A student uses letters from the word "ASSESSMENT" and the numbers 1,2 and 3 to form passwords for a personal computer. The passwords must start with an 'E' and end in the number '1'. Each password is 6 alphanumeric digits.
(a) How many passwords can be formed?
(b) What is the probability of selecting a password that contains 6 alphanumeric letters form 'A','R','C','H','1','P','E','L' ?
