Combinations on the TI83 or TI84 calculator Step 1: Type in the first number. In this case, the first number is 25. Step 2: Press [MATH] and go to the PRB menu. You can use the right arrow to select the menu at the top. Step 3: Select 3 nCr and press [ENTER] Step 4: Type the second number and press [ENTER] Other methods for calculating combinations. Click to see full answer. Likewise, how do you do combinations on a TI 84 Plus? The formula for a combination is: nCr = (n!)/(r!( to access the Math PROB menu or press [ALPHA][WINDOW] to access the shortcut menu. to access the probability menu where you will find the permutations and combinations commands. Using the TI-84 Plus, you must enter n, insert the command, and then enter r.Beside above, what is nCr math? Well combinations (nCr) simply means groping of particles or things in which their order is not taken into consideration(ie AB & BAis treated as same). Suppose there are 4 different balls (n) and you want to arrange them in the group of 2 (r), then total arrangements are. nCr=n! ÷[ r! Similarly, you may ask, what is the answer to 7c3? 7C3=7!/3!( 7-3)!= 5,040/6*4!= 5,040/6*24=5,040/144=35 ans.How many combinations of 3 items are there?There are, you see, 3 x 2 x 1 = 6 possible ways of arranging the three digits. Therefore in that set of 720 possibilities, each unique combination of three digits is represented 6 times. So we just divide by 6.
