So in this question, we have this cumulative distribution function, one minus the exponential function of minus 2x for every x that is positive.
00:11
So here, basically, we need to first find what is the pdf, the probability density function.
00:17
So the pdf here, because this function here is continuous in all the values of x, which is positive in this case, this is given by the derivative of the derivative, of this cumulative distribution function, which with respect to x, which basically means that we should derive this part, because this is a constant, like the one.
00:42
So if you derive the exponential, you're gonna get that we have a minus here, but then when we derive just the explanation, we have that this minus two will fall.
00:54
Then we need to repeat what we have...
