Hello,

I am trying to understand the math logic behind Math.random().

For example, take this equation:

Math.floor(Math.random() * 6 ) +1

Now we will get a random number between 1-6, but WHY?

This is my understanding so far:

Math.random will generate a number between 0-1, but never 1. So, if we add Math.floor, that will round the number down. Then we multiply whatever number that is by 6 and add 1. I don't understand how this produces whole numbers between 1-6. Something is missing in my understanding!

Thanks! Liz
