    Can anybody confirm that it is NOT possible to find chi squared probabilities on the Casio fx-991 EX calculator? Alternatively please tell me how.

    Adam has correctly summed up the situation. If you want a calculator that does this (including contingency tables) then get a TI-Nspire CX, which also has two very useful inverse binomial features.
  5. Or the Casio fxCG50 which has Chi squared probabilities and in the test section will calculate the measure of goodness of fit as well from values that you put into the table
