# Possible Outcomes Calculator

The chances of an event to occur is called as the possible outcome. Consider, you toss a coin once, the chance of occurring a head is 1 and chance of occurring a tail is 1. Hence, the number of possible outcomes is 2. Selecting items from a set without considering the order is called as combination. If the order of selection is considered, it is said to be permutation. Find the possible outcomes with order, repetition and without order, repetition using this calculator.

#### Formula:

s = r^{n} ( Case 1 )
s = n! / ( n - r! ) ( Case 2 )
s = ( n + r - 1 )! / ( r! * ( n - 1 )! ) ( Case 3 )
s = n! / (( n - r )! * r!) ( Case 4 )
**Where,**
s = Combination or Permutation
n = Total Number of Events
r = Number of value be Selected
** Note:**
Case 1 : Order is Important and Repetition is Allowed
Case 2 : Order is Important and Repetition is Notallowed
Case 3 : Order is Not Important and Repetition is Allowed
Case 4 : Order is Not Important and Repetition is Notallowed
