Votes____________________Number of Precincts______frequency
0-99----------------------3-------------------------3/75=1/25=.04
100-199-------------------10------------------------10/75=2/15=.1333
200-299-------------------25------------------------25/75=1/3=.3333

:
Fewer than 100 would be (0-99)---3/75=1/25=.04
At least 300 would be (300-499)---15/75+22/75=37/75=.49333
No fewer than 100 votes is (100-499)---10/75+25/75+15/75+22/75=72/75=24/25=.96

Happy Calculating!!!
