PROBABILITY DISTRIBUTION EASYCALCULATOR SERIES

These are also known as Bernoulli trials and thus a Binomial distribution is the result of a sequence of Bernoulli trials. The binomial distribution X~Bin(n,p) is a probability distribution which results from the number of events in a sequence of n independent experiments with a binary / Boolean outcome: true or false, yes or no, event or no event, success or failure.

PROBABILITY DISTRIBUTION EASYCALCULATOR TRIAL

Sequences of Bernoulli trials: trials in which the outcome is either 1 or 0 with the same probability on each trial result in and are modelled as binomial distribution so any such problem is one which can be solved using the above tool: it essentially doubles as a coin flip calculator. Note that this example doesn't apply if you are buying tickets for a single lottery draw (the events are not independent). For example, if you know you have a 1% chance (1 in 100) to get a prize on each draw of a lottery, you can compute how many draws you need to participate in to be 99.99% certain you win at least 1 prize ( 917 draws). Under the same conditions you can use the binomial probability distribution calculator above to compute the number of attempts you would need to see x or more outcomes of interest (successes, events).

For example, you can compute the probability of observing exactly 5 heads from 10 coin tosses of a fair coin (24.61%), of rolling more than 2 sixes in a series of 20 dice rolls (67.13%) and so on. In other words, X must be a random variable generated by a process which results in Binomially-distributed, Independent and Identically Distributed outcomes (BiIID). As long as the procedure generating the event conforms to the random variable model under a Binomial distribution the calculator applies. as 0.5 or 1/2, 1/6 and so on), the number of trials and the number of events you want the probability calculated for. Simply enter the probability of observing an event (outcome of interest, success) on a single trial (e.g. You can use this tool to solve either for the exact probability of observing exactly x events in n trials, or the cumulative probability of observing X в‰¤ x, or the cumulative probabilities of observing X x.
