This is a simple example in a text book, I haven't done probability since High school and probability being all too confusing... I cannot seem to overcome this problem. Here's the problem:(adsbygoogle = window.adsbygoogle || []).push({});

a)Assumekcar accidents occured inndays. Assume that accidents are equally likely on any day. Let A = event that one accident occured each day. What isP(A)?

The solution is given as below:

Solution:[tex]P(A) = \frac{n(n-1)...(n-k+1)}_{n^k}[/tex]

Can someone explain this solution or the process of obtaining this solution in plain english? Thanks.
