Webbthat you can get the correct solution by using P(n,r). FACT: Any problem that could be solved by using P(n,r) could also be solved with the FCP. The advantage to using P(n,r) is that in some cases we can avoid having to multiply lots of numbers. Conversely, there are problems that can be solved with the FCP but can't be solved using P(n,r). how to create test dataWebbFind the probability of each event to occur. Solution: Let us say the events of getting two heads, one head and no head by E 1, E 2 and E 3, respectively.
