This question already has an answer here:




  • Graphics file extensions and their order of inclusion when not specified

We usually write something like 



includegraphics{image}


instead of:



includegraphics{image.png}


That is, includegraphics does not usually require a file extension such as .png .pdf .jpg, etc... That is,



Suppose that I have all of the following files in the same directory. Which file will includegraphics embed?



my_pic.jpg

my_pic.psd

my_pic.png

my_pic.pdf

my_pic.jpeg

It depends on the engine. With pdftex the current list (which you can find in pdftex.def) is:



defGin@extensions{%

  .pdf,.png,.jpg,.mps,.jpeg,.jbig2,.jb2,%

  .PDF,.PNG,.JPG,.JPEG,.JBIG2,.JB2%

}


That means that e.g. pdf will be prefered, then png etc.

    @Sigur the user documentation tells you how to set the list texdoc graphics section 4.5 DeclareGraphicsExtensions the default is driver specific and initially there were dozens of different drivers they are not documented in the core documentation.

As documented in the graphics guide (section 4.5), this is user settable.



If you have



DeclareGraphicsExtensions{.pdf,.png}


in your document then it will just try .pdf then .png in that order, and ignore the rest.



The default value as shown in Ulrike's answer is set in the driver file for the option you are using. (Using a lower level def syntax rather than DeclareGraphicsExtensions because the driver files might be loaded by the color package, before DeclareGraphicsExtensions is defined.)

            Probability when a professor distributes a quiz and homework assignment to a class of n students.

            0 0 $begingroup$ Need help with this problem. Suppose our lazy professor collects a quiz and a homework assignment from a class of n students one day, then distributes both the quizzes and the homework assignments back to the class in a random fashion for grading. Each student receives one quiz and one homework assignment to grade. (a) What is the probability that every student receives someone else's quiz to grade, and someone else's homework to grade? (b) What is the probability that no student receives both their own quiz and their own homework assignment to grade? In this case, some students may receive their own quiz, and others may receive their own homework assignment. (c) Compute the limiting probability as n approaches infinity in each case. ...
