I am using sharp EL-531WH. i want to calculate permutation and combination straight from the calculater, but i dont no how. I miss placed my instruction manual after i bought the calculater.plz help.
Hello,
Use the sequence [2ndF][nPr] for permutations and [2ndF][nCr] for combinations.
Exemples: 10(nPr)3 is entered as 10[2ndF][nPr]3 [=] gives 720
5(nCr)2 is entered as 5 [2ndF][nCr] 2 [=] gives 10
Hope it helps.
