Courses Plus Student 2,305 PointsMath.floor(Math.random() * 256 We wont be getting 256 with this line, will we?
since 1 is exclusive from Math.random(). Are we eliminating the possibility of getting 256?

13,366 PointsYes, that's correct. Math.random() doesn't include 1, so we wouldn't get 256.

6,475 PointsHi Wuen Han Lee,
You are right. We won't get 256. There are two reasons for this:
1) As Bryan Laraway stated already, Math.random() does not include 1
2) The Math.floor() function will round down a number to the lower integer. For example, let's take the number 1.6 so Math.floor(1.6) = 1. So since this function doesn't round up but only down, that's another reason we won't 'reach' 256.
Hope that helps.

17,182 PointsYes, But if you want to get 256, That means 255 will be your maximum random number generated which is the highest decimal value for color (255)
