BEETLE
To make a beetle, you flip a coin. Heads allows you to add one of the five parts - body, head, eyes, antenna, legs. The data for the number of flips needed are stored in lists 1 and 2.

BIAS
Flip three different coins a chosen number of times and see the numbers of heads. Are any of the coins biased? This program provides a useful resource for teaching hypothesis testing.

COIN1
Flip a coin between 1 and 7 times.

DICE6
A die is thrown until a 6 appears. The data for the number of throws needed are stored in lists 1 and 2.

LIKE1, LIKE2, LIKE3
Classroom introduction to addition and subtraction of like terms.

NORMAL
Enter the mean and the standard deviation to draw the graph of the probability density function (stored in Y1). The usual calculator features can then be used to calculate probabilities as areas under the curve.

ORBIT
Plot orbits for the recursive relation z->z²+c. Enter value of c (real or complex) and the seed (initial value of z). Press any key to view the next value of z and its position on the complex plane.

PIVOT
Use this program with the Gauss Jordan method of solving linear equations or with the simplex method of linear programming. The augmented matrix is entered in matrix mode as matrix A. Run the program and select the pivot row and pivot column. The program divides the pivot row by the pivot element and uses row operations to set the pivot column to 0's (except for the pivot element).
