Please answer questions 3.8, 3.9, and 3.10

Exercise 3.8 How many integers 1 sa s 10000 are divisible by 2, 3, or 5? Exercise 3.9 Let V be a set with VI = k. What is the number of dicts d with len(d) == n and d.values() in V? 3.5 Maps Exercise 3.10 The values of the roman numerals are given by the dict {'M' :1000, 'D':500, 'C' :100, 'L':50,'X':10,'V':5,'I':1} Write a function highest that returns the index of the first occurance of the highest-value numeral: highest('XII') = 0, highest('CDLVCDXII') = 1. Write a function roman that translates a number from roman to decimal as fol- lows. In roman notation, numerals are initally written left to right in decreasing order, >>> roman('MCCLXII) = 1000 + 200 + 50 + 10 + 2 True Ir, however, a numeral has greater value than numerals in a block of numerals to its left, then that block is counted with a minus. Thus roman('IX') is -1 + 10 = 9, and >>> roman('MCLDII') == 1000 - (108+50) +500 + 2 True
