- I am making passwords for my computer systems, using ‘code symbols’ as a cyber-security caution. I am only going to use 5 out of 6 letters for my codes from the letters G, H, I, J, K, and L. From this, answer the following questions:
c. How many code symbols can I make (5 out of 6) if they cannot be repeated but must begin with the letter ‘K’?
d. How many code symbols can I make if the letters cannot be repeated but must end with I, G and H?
