      What's the Probability of Obtaining Exactly 3 Heads If A Fair Coin Is Tossed 4 Times?
      Applications
IV. Sum of the Probabilities and the Binomial Mean
      The Sum of The Probabilities Is One.
      The Expected Value Is The Mean.
      The Mean, Expected Value, Is (n)(p).
      Why the mean, expected value, is (n)(p)
V.   Examples
VI. Use the Normal to Compute the Binomial on a Calculator
 
A Binomial Distribution, Brief Summary
 
      Flip a coin 4 times (or flip 4 coins) and count the number of heads. The coin doesn't even need to be a fair coin (in which a tail is as likely as a head). The experiment is described by a binomial distribution.
 
      An only two-possible-outcome experiment, repeated a certain number of independent times is called binomial. The distribution or function has as a variable x, the number of successes. The other required parameters are n, the number of independent trials, and p, the probability of success. The probability of failure on each trial is q, or 1 - p.
      The mean and standard deviation of a BINOMIAL DISTRIBUTION are stated below.
