On a TI 36X calculator what button is the same as the PRB for solving probability
That depends on what you mean by "solve probability." You could study probability for a year in college and not come close to covering all the types of probability problems. Do you want the number of combinations or permutations? The upper or lower tail of some probability distribution? The inverse distribution?

Use the inverse log key sequences "2nd LN" or "2nd LOG" depending on whether you are using natural logs or logs to base 10

I assume you are speaking of solving a system of equations with a number of unknowns. If not, please correct me. Here's an example in practice:
If you have a system of 3 equations with 3 unknowns, you would set up your matrix so that the coefficients of each variable for a particular equation are on one row. So, given equations x + y + z = 0, 2x + 3y - 4z = 1, x + -z = -1 you would type the following into your calculator: [[1,1,1,0][2,3,-4,1][1,0,-1,-1]] and press enter to make sure you typed it correctly. notice that in the third row there is a zero, since we have zero time y for the third equation. Then row-reduce the matrix (2nd > 5 > 4 > 4 or in the CATALOG as rref). You should get out the matrix [[1,0,0,-1][0,1,0,1][0,0,1,0]]. This says that x=-1 y = 1 z=0 since my first column contained the coefficients for the x variable, the second for the y variable, and the third for the z variable. The last column contains the solution, the part on the other side of the equals sign.
Hope this helps! For more reading (from someone else; I just made this one up), check out the Wikipedia articles on Gaussian elimination and Systems of linear equations
SOURCE: solving multiple non-linear equations
Type it like this: solve( equation1 and equation2 and moreEquations, {list of variables to solve for})
Put all of your equations right after the opening parenthesis separated by the word and, then a comma, then within curly braces each variable you want to solve for each separated by a comma.

Hi,
There is a dedicated key for the function. The key is labeled as on the third line of the table below. You enter a positive number, press the key and then hit [=]. Hope it helps.
SOURCE: exponent key on the TI-36x Calculator
On the TI-36X there is no rooftop key, there is a yx key. This key is two keys below the on button. To use it, put the number in, press the yx key, put the exponent in, press the equal button.
