Maths Distributions

1. Core

   • Binomial
     • Let x be the number of successes out of n trials
       • X can take the values 0,1,2...n
       • X~Bin(trials, probability of success)
   • Poisson
     • Let x be the number of occurrences in a given interval of time
       • X can take the values of 0,1,2,3...
       • X~Po(Average number of occurrences in a given time)

2. Stats Option

   • Negative Binomial
     • x is the number of trials until the rth success
       • x=r, r+1, r+2...
       • x~NB(r,probability of success)
   • Geometric
     • Let x be the number of trials until the first success
       • x can take the values of 1,2,3...
       • X~Geo(Probability of first success)
