Answer:
Step-by-step explanation:
so there are 13 multiples of three and there's 40 numbers in total. 40 times 2.5 is 100. you do 13 times 2.5 which equals 32.5 percent chance of getting a multiple of three. so you do 100 minus 32.5= 67.5 percent chance of not getting a multiple of three.
Hope this helps:)
