When counting in Roman numerals from

1 to 2500, which Roman numeral "digit"

(I, V, X, L, C, D, M) is used in the fewest numbers?

*SOLUTION:*

*"D" (500) is used the fewest times.*

*Only 1101 of the Roman numerals from 1-2500 use a "D."*

*By comparison, "I" appears at least once in 2000 of the Roman numerals from 1 to 2500. Here's the rest of the list:
V - 1250
X - 2050
L - 1250
C - 2050
D - 1101
M - 1601*
