A botanist is doing fieldwork assigns an eight-character alphanumeric code to each sample collected. The first character must be 6, 7, or 8; the next three characters can be any capital letter, A through Z; the fifth character could be any digit except for 0; and the rest of the characters can be any capital letter, B through K. Digits and letters can be repeated. Determine how many possible ID numbers there are using the fundamental counting principle, and explain each step. Show work for all steps Thanks
In order to investigate a serious cyber security fraud affecting all Estonian residents, we need to generate and test all in principle possible potential personal identification codes of all Estonian residents. We must certainly do it in such a way that it would certainly cover all currently living residents of Estonia. Estonian personal identification code (for example 38506301653) is formed as follows: - first digit (3) indicates both the gender and birth century; - second and third digits (85) represent the last two digits of birth year (1985); - fourth and fifth digits (06) represent the month of birth (June); - sixth and seventh digits (30) represent the date of birth (30); - eighth, ninth and tenth digits (165) simply represent the sequence number (the combination 000 is not used); - eleventh digit (3) is an error correction code calculated from the previous ten digits according to a certain deterministic algorithm. We've prepared a small test serie and we know that it takes 1…
