| Question | Answer |
|---|---|
| Whgat are the 4 Binomial Experiment conditions? | 1. (n) Repeated a fixed number of trials. Each trial is independent of other trials. 2. Only 2 outcomes: success (S) and failure (F) 3. P(S) is the same for each trial 4. random variable (x) counts # of successful trials |
| What do n, p, q, and x represent? | n: # of times trial repeated p: P(S) q: P(F) x: # of success in n trials |
| What's the Binomial probability formula? | P(x)=nCx p^s q^(n-x)=[n!/(n-x)!x!]p^x q^(n-x) |
