The Binomial Distribution | Probability and Statistics<\/span><\/h3>\r\n

 <\/p>\r\n

What is a Binomial Distribution<\/a>, and how<\/a> does it work?<\/strong><\/p>\r\n\r\n\r\n\r\n

A binomial distribution can be thought of as the likelihood of a Positive or FAILURE outcome in a multiple-repeated experiment or sample. The binomial distribution is a type of probability distribution with two possible outcomes (the prefix “bi” means “two” or “twice”). A coin flip, for example, has only two possible outcomes: heads or tails, and a test can have two possible outcomes.<\/p>\r\n\r\n\r\n\r\n

\"\"<\/figure>\r\n\r\n\r\n\r\n\r\n\r\n

 <\/p>\r\n\r\n\r\n\r\n

A Binomial Distribution shows either (S)uccess or (F)ailure.<\/em><\/p>\r\n\r\n\r\n\r\n

\u2022 The number of times the experiment runs is expressed by the first variable in the binomial formula, n.<\/p>\r\n\r\n\r\n\r\n

\u2022 The likelihood of one particular outcome is represented by the second variable, p.<\/p>\r\n\r\n\r\n\r\n

Consider the case where you wanted to know the chances of rolling a 1 on a die. The chance of rolling a one on any throw is 1\/6 if you roll a die 20 times. If you roll 20 times, you’ll get a binomial distribution of (n=20, p=1\/6). FAILURE would be \u201croll something else\u201d and SUCCESS would be \u201croll a one.\u201d \u00a0The binomial distribution would become (n=20, p=1\/2) if the result was the likelihood of the die landing on an even number. This is due to the fact that tossing an even number has a half-probability.<\/p>\r\n\r\n\r\n\r\n

Criteria<\/h3>\r\n\r\n\r\n\r\n

The following three conditions must also be met by binomial distributions.:<\/p>\r\n\r\n\r\n\r\n

    \r\n
  1. The number of observations or trials is fixed.<\/strong>\u00a0To put it another way, you can only determine the likelihood of anything occurring if you do it a certain amount of times. This is self-evident: if you flip a coin once, you have a 50% chance of having tails. If you flip a coin 20 times, the chances of having tails are really close to 100 percent.<\/li>\r\n
  2. Each observation or trial is distinct from the others. To put it another way, none of the trials have any bearing on the likelihood of the next trial.<\/strong><\/li>\r\n
  3. From one trial to the next<\/strong>, the likelihood of success (tails, heads, fail, or pass) is the same.<\/li>\r\n<\/ol>\r\n\r\n\r\n\r\n

    Binomial Distribution<\/strong> is a\u00a0Discrete Distribution<\/em>.<\/p>\r\n\r\n\r\n\r\n

    It defines the outcome of binary situations, such as a coin flip, where the outcome is either head or tails.<\/p>\r\n\r\n\r\n\r\n

    There are three parameters to it:<\/p>\r\n\r\n\r\n\r\n

    n stands for the number of trials.<\/p>\r\n\r\n\r\n\r\n

    p denotes the likelihood of each trial occurring (e.g. for toss of a coin 0.5 each).<\/p>\r\n\r\n\r\n\r\n

    Uniform Distribution<\/strong><\/p>\r\n\r\n\r\n\r\n

    When any occurrence has an equal chance of occurring, this is referred to as likelihood.<\/p>\r\n\r\n\r\n\r\n

    For instance, random number generation.<\/p>\r\n\r\n\r\n\r\n

    There are three parameters to it:<\/p>\r\n\r\n\r\n\r\n

    a – lower bound – defaults to 0.0; b – upper bound – defaults to 1.0.<\/p>\r\n
