The Story Behind Random State 42To generate a set of five random integers between 10 and 25 (inclusive):
| 1. | Press », then press ~ until you highlight PROB. |
| 2. | Press † until you highlight 5: randInt(, then [enter]. |
| 3. | Enter the lower integer, then [enter]. |
| 4. | Enter the upper integer, then [enter]. |
| 5. | Enter the number of integers (n), then [enter]. |
| 6. | Press [enter] to Paste. |
| 7. | Press [enter] again to see the random set of integers. |
Note:
| • | With each rand execution, the TI-84 Plus CE generates the same random-number sequence for a given seed value. The TI-84 Plus CE factory-set seed value for rand is 0. To generate a different random-number sequence, store any nonzero seed value to rand. To restore the factory-set seed value, store 0 to rand, or reset the defaults by going to yL7:Reset... 2:Defaults.... |
| • | The seed value also affects randInt(, randNorm(, and randBin( instructions. |
