Binomial Distribution

  • There are 2 possible outcomes
  • There are 2 outcomes which have probabilities P and P-1
  • P + Q=1 --> there are no other possible outcomes
  • probability in any trial is independent of probability in previous trial
  • variable (X) is random

1. Always define X 
2. X~(n,p)
3. P(X=r) = nCr x Pr x (1- P) n-r 

B~(n,p) the expectation for the number of success' is np
