Use the EE (enter exponent) key (2nd-shift of the key just above the 7) to enter the exponent. Use the (-) key just to the right of the decimal point to enter a negative number.

The - key subtracts one number from another. The (-) key enters a negative number.

You should consult a Linear Algebra book. Besides, these calculator cannot handle matrices of dimensions 4x4 or higher . With matrices of dimension 3x3 and less it is probably easier to use the Cramer rules directly.

Let us start with a review of the formula for the binomial distribution

But n!/(r!(n-r)!)=(nCr) you get
f(r;n,p)= (nCr)x(p^r)x(1-p)^(n-r)

Exemple : n=25, r=6, p=0.7

f(6;25,0.7)= 25 [PRB] [-->] 6 [ x ] {0.7[ ^] 6 }[ x ]{0.3[ ^ ]19}

The arrow means a horizontal scroll once to select the (nCr) function. [ x ] stands for the multiplication sign.
[ ^] is the raise to the power key
The { } are used here as parentheses to make formula legible.
