To determine the number of permutations and combinations
possible when selecting four people from a group of 10
Permutations: 10 1*( n P r ) 4 = 5040
Combinations: 10 1/( n C r ) 4 = 210
To perform the following calculations when Fix 3 is selected for the
number of display digits: 10 ÷ 3 × 3 and Rnd(10 ÷ 3) × 3 b

10(Rnd) 10 / 3 )* 3 = 9.999
Statistical Calculations (STAT)
To start a statistical calculation, perform the key operation N2(STAT)
to enter the STAT Mode and then use the screen that appears to select the
type of calculation you want to perform.
To select this type of statistical calculation:
