You can substitute a twenty-sided die roll with standard dice using the handy tables below for two six-sided or three six-sided dice. Note that percentages were chosen to be as close as possible (either up or down) to the original percentage.
By the way, the last row of each table (the "100%" row) was included for warrior characters.
