Any video link for this chapter? I couldn't figure out the inclusive part.

When looking for a total number of something numbered from V1 to V2 then we have to use the "inclusive counting technique." This means that we have to subtract V1(the smallest number) from V2 (the biggest number) and then add 1. Then we can infer that from 101 to 350 we have 250 numbers (350 - 101)= 249 + 1 = 250. We also know that in this range (101 to 350), only numbers from 200 to 299 have a number with a hundreds digit of 2. Again, we can infer that we have 100 numbers (299 - 200) = 99 + 1 = 100. So we know that the probability is (# of possible outcomes /# of total possibilities) = 100/250 = 2/5.
