How will I find P(10, 4)? That is a probability problem right?

That's usually notation for a the number of permutations when selecting 4 objects from 10.
P(10,4) = 10!/(10-4)!
= 5040
There are 5040 ways to select 4 objects from a total of 10 where order of these objects matter.
The general formula is
P(n, k) = n!/(n-k)!

from the information i was taught...yes that is a probability problem saying...What is the probability of 10 and 4 of what ever ur question is saying....
Let's say I had 5 cards. 2 cards had the number 10, 1 card had the number 4, and 2 cards had the number 3.
They are wanting to know P(10, 4)...which means "What is the probabilty that you will draw a 10 or a 4?"
you have 5 cards...2 have #10 and 1 has #4...you can draw EITHER a 10 OR a 4...so you combine those two combinations (2+1=3)...
...so P(10, 4)= 3/5

This is not a probability problem, but a counting problem,--the number of ways 4 items can be arranged from 10 items (permutations). blahb31 got the answer

looks like an abbreviated ti-8? thing where it tells you possible combinations
