To set up your Texet scientific calculator Albert EVS, first ensure it is powered on by pressing the "ON" button. Then, you can adjust settings like the number of decimal places or the angle measurement (degrees/radians) by pressing the "MODE" button and navigating through the options using the arrow keys. Finally, confirm the desired settings by pressing "ENTER." Always refer to the user manual for specific instructions tailored to your model.
you have to press F<-->D button, short for fractions - to - decimals
There is a choice of 14 students for the first; For each of these there is a choice of any of the remaining 13 students in the second place, making 14 × 13 choices so far; for each of these there is a choice of any of the remaining 12 students in the second place, making 14 × 13 × 12 choices so far; and so on, until all 5 places have been filled which has 14 × 13 × 12 × 11 × 10 = 240,240 different ways. ------------------------------------------------------------------------------------------------------------------------- This is a mathematical Permutation where there is a selection of r items from a group of n items. It can be calculated as: nPr = n! / (n - r)! Where n! means "n factorial" and is n × (n - 1) × (n - 2) × ... × 2 × 1. 0! is defined to be 1. You will find it on most scientific calculators. On the Casio fx-83GT Plus, fx-85ES, fx-115MS it is found as [shift] [×]; on the Casio fx-83WA and Texet aLBΣRT³ it is found as [shift] [nCr]; for other calculators you'll need to read the manual (those are the only ones I have [handy] on which I can check). If you do not have the nPr function, you should have the factorial (!) function and can use the formula above.
