Bit confused with whether the function work or not

what if math.random generate a number close to 0.99, with the low number being 10 and the high being 100.

there will be chances where it is actually a number of 100 instead 11 to 99?

The possible range of numbers depends on both the formula used and the parameters given. The formula shown in the video is inclusive of the limits, so if you provide 10 and 100 as the limits, you could indeed get the number 10 as a result, or 100, or any number in between.

There are other formulas that are exclusive of the limits, so 10 and 100 would give you a number from 11 to 99, but that formula is not shown in the course video.

oh that makes sense now i thought they are developing a formula for random number up to 99 only
