Bernoulli Trials---I

• A series of Bernoulli Trials is the generalized coin tossing problem.

• We have a sequence of independent ``trials''---each of which has only two outcomes:

  Success or ``heads'': probability p

  Failure or ``tails'': probability q

  where, of course p+q=1.

• Afficiando's of affirmative action and women's lib will note that generations of math books have downgraded tails compared to heads.

• Anyhow, we follow in their footsteps and set as the probability of k successes in n trials.
