Input n, press 2nd [nCr], input r, press =.

For example, to calculate the number of thirteen-card bridge hands that can be dealt from a deck of 52 cards:

5 2 2nd [nCr] 1 3 =

SOURCE: How to do nPr or nCr on TI-30x Solar (scientific calc.)

If you have an older version on the TI30x Solar (not TI30Xa or newer) then you must use a different key sequence for nPr/nCr.

52 [2nd][x/y] 5 [2nd][nCr] gives 2598960 (the x/y button is above the Pi symbol on my version).

8 [2nd][x/y] 3 [2nd][nPr] gives 336

This took me forever to find out, so hopefully it will help someone!

It means the calculator is current set to the degrees mode. Trigonometric function depend on how you measure the angle. The most common units are degrees, radians, and grads. To change the mode on the 30Xa, press the DRG key to cycle through them.

Sorry, the TI-30x doesn't have the cumulative normal probability function built-in.

To calculate the number of combinations of n items taken r at a time, enter n, press x-y, enter r, then press 3rd [nCr] =. For example, to find the number of possible five-card poker hands, press

5 2 x-y 5 3rd [nCr] =

x-y is the x-exchange-y key just below the blue 2nd key.

5 2 x-y 5 3rd [nCr] =

x-y is the x-exchange-y key just below the blue 2nd key.

Yes. Use the 2nd [nCr] function.

52 2nd [nCr] 5 = will calculate the number of 5-card poker hands that can be dealt from a deck of 52 cards.

52 2nd [nCr] 5 = will calculate the number of 5-card poker hands that can be dealt from a deck of 52 cards.

How many ways can you select 3 members out of 9 republicans: nCr (9,3)

How many ways can you select 3 members out of 10 democrats: nCr(10,3)

For each single choice of 3 reps you have 1*nCr(10,3) possible subcommittees.

Hence the total number of possible suncommittes is nCr(9,3)*nCr(10,3)

Explictitly

# of possible subcommittees is [9!/(3!*6!)]*[10!/(3!*7!)] or 10080

To calculate you can use the explict formula above or use the nCr function of your calculator

To access the nCr( function press [2nd][5] (MATH) [7:Probability][3:nCr]

You can also just type the name of the command respecting the case ( C must be upper case)
