CASIO

Inputting a value followed by % command causes the input value to become a percent.

Example 1: 150 × 20% = 30

• 15020
  – [Probability] > [%]
  
• 

Example 2: Calculate what percentage of 880 is 660. (75%)

• 660880
  – [Probability] > [%]
  
• 

Example 3: Discount 3500 by 25%. (2625)

• 3500350025
  – [Probability] > [%]
  
• 

This function obtains the factorials of a value that is zero or a positive integer.

Example: (5 + 3)! = 40320

• 53
  – [Probability] > [Factorial(!)]
  
• 

Permutation (nPr) and combination (nCr) functions.

Example: To determine the number of permutations and combinations possible when selecting four people from a group of 10

Permutations:

• 10
  – [Probability] > [Permutation(P)]
  4
• 

Combinations:

• 10
  – [Probability] > [Combination(C)]
  4
• 

This function generates a pseudo random number in the range of 0.000 to 0.999. The result is displayed as a fraction when MathI/MathO is selected for Input/Output on the SETTINGS menu.

Example: To obtain random three-digit integers

• 1000
  – [Probability] > [Random Number]
  
• 

• (The result differs with each execution.)

This function generates a pseudo random integer between a specified start value and end value.

Example: To generate random integers in the range of 1 to 6

• – [Probability] > [Random Integer]
  1(,)6
  
• 

• (The result differs with each execution.)
