At a family gather, 23 people are trying to fit into several cares. your car holds 6 people. How many different groups of 6 could you take in your car? I got 19769460480..is that right O.o?

Parth (parthkohli):

You're choosing 6 from 23, so 23 choose 6 or 23c6

OpenStudy (anonymous):

23*22*21..etc till 6 numbers down multiplied together?

Parth (parthkohli):

My browser crashed... :'(

Parth (parthkohli):

Okay, so that'll make: \(\Large \color{Black}{\Rightarrow {23! \over (23 - 6)! \times 6!} }\) \(\Large \color{Black}{\Rightarrow {23! \over 17! \times 6!} }\) \(\Large \color{Black}{\Rightarrow {23 * 22 * 21 * 20 * 19 * 18 \over 6!} }\) 17! got cancelled. \(\Large \color{Black}{\Rightarrow {23 \times 22 \times 21 \times 20 \times 19 \times 18 \over 6 \times 5 \times 4 \times 3 \times 2} }\)

Parth (parthkohli):

Parth (parthkohli):
