The objective of Predictive Calculator is to provide solutions for some of the basic statistical problems. Predictive Calculator will help you solve basic math problems related to permutations, combinations and factorials. A sample command will be something like "combinations for selecting 3 out of 9 items." or "permutations for selecting 12 out of 15 items" Only numbers less than 20 are handled as bigger numbers result in exponential answers, which hold no relevance
