Although highly disputed as one of the most difficult subjects in school, it's also one of the most important, being at the core of construction projects and even computer programs. Expressions become complicated, and you need to use them wisely, depending on the task at hand. Dedicated to probability,  Binomial Distribution Calculator is a straightforward application with a name that speaks for itself.

This binomial distribution is used in statistics and yes or no experiments in order to precisely determine the chance of success, based on different parameters for number of trials, probability, as well as number of times favorable conditions need to be encountered. In other words, it helps you determine your chances to get tails when tossing a coin, given you know the coin's probability value.

Running the application brings up a fairly simple and compact main window that gradually expand to reveal info so that it doesn't take up precious desktop space with empty info fields. As mentioned above, you're asked to define three values, such as trials and successes through numerical values, as well as the probability percentage by dragging a slider around. The success rate can either be specified as a single value or interval.

Hitting the “determine” button reveals the result in its mathematical form. For different results or types of experiments, the application can determine the cumulative result in case you're using an interval for success. If the distribution box is checked, the main window expands to display each try and its rate of success.

What's more, you can generate a visual representation in the form of a bar graph at the press of a button. Sadly, there are no implemented export options, so you need to keep either a text editor at hand or hit the “Print Screen” button on your keyboard to grab the graph.

Taking everything into consideration, we can safely state that  Binomial Distribution Calculator does a pretty good job overall. Even if the feature set comprises of a few input fields and no export options whatsoever, it lives up to expectations by providing a fast, reliable and efficient way to calculate chances of success.
