For a digital measuring device, rounding errors have uniform distribution between negative 0 .07 and 0 .13 millimeters.
00:10
Find the probability that the rounding error, so we'll write it this way, that the error is greater than or equal to, negative 0 .03.
00:25
Okay, so when we have a uniform distribution, we can find our mu, and we can find our standard deviation.
00:35
So if we add our two values together, so in this case, negative 0 .07 plus 0 .13, and then divide by 2, we'll get our mu.
00:47
So i'm going to go ahead and erase this symbol for standard deviation because i wrote it a little too close.
00:54
So that works out to be 0 .03.
00:58
And then our standard deviation, we're going to take our second value, so 0 .13, and we'll subtract...
