A company uses one letter followed by four digits for product codes. If any of the

Question

letters A–Z is allowed in the first position, and any of the digits 0–9 in the next four
positions, how many different product codes are possible? (The letters and digits may be used more than once.)

Answer 1

There are 26 choices for the first letter and 10 choices for each of the four remaining digits. Thus, the total number of different product codes is:

26 x 10 x 10 x 10 x 10 = 26,000

Therefore, there are 26,000 different possible product codes.

26 x 10 x 10 x 10 x 10 = 260,000

26 x 10 x 10 x 10 x 10 = 260,000
