What is the meaning of the function notation R w?
. R is a function of w
How lines r and s intersect point w?
The answer depends on what lines r and s are, and where point w is.
Find the number of combinations of 10 things taken 6 at a time?
Try 151,600! Permutations & Combinations. P(n,r)=n!(n−r)! not P(n,r)=n!/(n!-r!)r! ?
How can you prove the combination formula?
Combination Formula ProofGENERIC:Let C(n,r) be the number of ways to generate unordered combinationsThe number of ordered combinations (i.e. r-permutations) is P(n,r)The number of ways to order a single one of those r-permutations P(r,r)The total number of unordered combinations is the total number of ordered combinations (i.e. r-permutations) divided by the number of ways to order each combinationThus, C(n,r) = P(n,r)/P(r,r) = [n!/(n-r)!]/r!/(r-r)!] = n!/r!(n(n-r)!SPECIFIC:Let C(52,5) be the number of ways to generate unordered poker handsThe number of ordered poker hands is P(52,5) = 311,875,200The number of ways to order a single poker hand is P(5,5) = 5! = 120The total number of unordered poker hands is the total number of ordered hands divided by the number of ways to order each handThus, C(52,5) = P(52,5)/P(5,5)
