Step-by-step explanation:
Range of horses = between 100 and 150
Dislike horses divisible by 3 and 5
Divisible by 3 or 5 = (100,102,105,108,110,111,114,115,117,120,123,125,126,129,130,132,135,138,140,141,144,145,147,150)
Counts of number between 100 and 150 divisible either by 3 or 5 = 24
Total Number counts between 100 and 150 = 51
Numner of horses Charlie can choose from:
