Can You Exclude a Specific Number When Generating Random Numbers in Mathematica?

Click For Summary
SUMMARY

The discussion focuses on generating random numbers in Mathematica while excluding a specific number, specifically the number 10. The user demonstrates the use of the RandomInteger function to generate a list of random integers between 1 and 20. To exclude the number 10, the user suggests using a conditional statement to filter the output or creating an array of numbers from which 10 is omitted. This approach ensures that the generated list does not include the excluded number.

PREREQUISITES
  • Familiarity with Mathematica programming language
  • Understanding of the RandomInteger function in Mathematica
  • Basic knowledge of conditional statements in programming
  • Concept of array manipulation in Mathematica
NEXT STEPS
  • Explore advanced features of RandomInteger in Mathematica
  • Learn about array filtering techniques in Mathematica
  • Investigate the use of conditional statements for data manipulation
  • Study random number generation algorithms in programming
USEFUL FOR

This discussion is beneficial for Mathematica users, programmers interested in random number generation, and anyone looking to manipulate lists while excluding specific values.

I am trying to create a list of 5 random numbers between 1 and 20

In[62]:= RandomInteger[{1, 20}, 5]

Out[62]:= {10, 11, 9, 8, 1}

But is it possible to exclude the number 10 from appearing?

I am more of an R person, but I'm sure there is some kind comparison operator. Something along the lines of

PHP:
if ($x != 10)
   print $x;

You can feed the output of the random number generator into the above code.

The ' != ' means 'not equal'.
 
You could choose a random index to an array of 19 numbers, which includes the numbers 1 thorugh 20, but not 10.
