"The CDF can be written as the probability of the lifetime being less than some value x" That helped me soooo much, thanks!

Ok this is fantastic. My prof has the most round about ways of explaining probability densities. This really underlines the basic concepts and makes it much easier to tackle tougher problems, that included exponential distribution as a part of them. Thanks!

I'm confused.. at 10:00 you say "and that minus there, and that minus there gives a plus".. where are you getting the other minus? I can only see a 1 - (1-e^(-lambda x)) which should give -e^(-lambda x) ??

I thought because exponential distribution deals with continuous data, that you could not use less/more than or equal to, rather just less than or more than. Because with continuous data the probability of you being exactly on the point of a discrete number such as having exactly 5 litres of fuel in ur tank, would be 0? correct me if I'm wrong

Good question - Remember that the exponential is a continuous distribution. P(X =k) is considered 0. If the distribution was *discrete* - then the problem you mentioned would arise.
@DragonflyStatistics
@DragonflyStatistics 11 жыл бұрын
As regards the Interval 1. P(Inside Interval) = 1-P(outside Interval) 2. P(Outside Interval) = P(Too High) + P(Too Low) It is common to all continuous distributions so not discussed here in detail

if you want to use the pdf you have to integrate .. which is the cdf.. less math to do
@akashray6447
@akashray6447 6 жыл бұрын
because pdf of a function is the probability per unit if you use it then it will not give you the probability ,instead if one uses the integration of pdf wrt "the unit" then you will get{(probability/unit)xunit} which will give you the probability also known as the cdf.

In continuous distributions P(X>=k) = P(X>k). Because doing Integral in a precise point is equal to 0.
