I am trying to figure out 200P50 I know that I use my calculator which is 200 nPr 50 but it says overflow is there a simpler way of doing this? (permutations)

Question

ddcamp · Answer

When finding nPr, you can use the equation:
$$\frac{ n! }{ (n-r)! }$$ to find the permutations.

ddcamp · Answer

$$\frac{ 200! }{ (200-50)! }=\frac{ 200! }{ 150! } =\frac{ 200\times199\times...\times151\times150\times149\times...\times3\times2\times1 }{ 150\times149\times...\times3\times2\times1 }\ = 200\times199\times...\times152\times151$$

anonymous · Answer

do you think that leaving it as 200!/150! will be a good enough answer?
