Calculates the probability for the multinomial distribution using a set of values and related probabilities
Determines how many (n) digit numbers can be formed using No Replacement, Unique Digits, as well as using only certain number 0 - 9.
Determines various items of a parabola that you enter: Focus, open direction, horizontal or vertical, and directrix.
Determines the least amount of coins possible to attain a dollar value.
Compares 2 coupons, a flat dollar amount off and a percentage off and determines the best deal. If the dollar amount wins, the calculator also shows the percentage off needed to match the dollar deal.
