I would like to do LN 25.21/25.20 on the calculator. It suppose to equal to 0.00397. i tired the division first then, 2nd and LN. could not arrive to the same result.
also, if you have a binomial model equation (P(X)= P(X=X)=(nCx) Px(1-P)n-x. Please note that Px is suppose to be to the power and n-x also to the power. How do you do 10C5 on the calculator?
I have the BAII Plus Texas Instrument.
