EXAMPLE 43 Calculating the number of permutations and combinations using technology

Use the TI-83/84 and Excel to calculate the following:

  1.  9P6
  2.  10C7

Solution

We use the instructions provided in the Step-by-Step Technology Guide at the end of this section (page 302).

  1. From Figures 19a and 19b, we find that  9P6=60,480.
