To use these probability 
					options, access the Math key.  Arrow to the right to find the  PRB (probability) menu.  
On this screen you will find:  
              #2  nPr  permutation 
              #3  nCr  
					combination 
              #4  !  factorial 
  | 
					
					  
  | 
				 
			 
			Each of these functions, requires 
			that you enter a value FIRST and 
			then access the function.  For example: 
			
				
					
						Permutations 
						and Combinations are handled in the same manner: 
                    Compute  6P3 and 5C2
                        
						  
						    Go to the HOME screen.   
					      Enter your first value (for this example, 6  or  
						    5) 
					      Hit the MATH key, 
						    arrow to the right to PRB. 
					      Choose #2, nPr   or  #3 nCr 
					      Enter your second value (for this example, 3  or  
						    2) 
				      Press Enter.  | 
						
						  
  | 
					 
					
						| Factorial:       Compute  6!
					    
						   
						    Go to the  HOME screen.   
					        Enter your value first (for this example, 6) 
					        Hit the MATH key, 
						      arrow to the right to PRB. 
					        Choose #4, ! 
			          Press Enter.  |
