The RANDOM function uses a seed to generate a random number. Each random
number generated becomes the seed for the next random number. Therefore, a
sequence of random numbers can be repeated by starting with the same seed. You
can store a new seed with the SEED function. If memory is cleared, the seed is reset
to zero. A seed of zero will result in the calculator generating its own seed.
Example:
Combinations of People.
A company employing 14 women and 10 men is forming a six–person safety
committee. How many different combinations of people are possible?
