Bernoulli Experiment PRO
Read full descriptionHide full description
This app calculates the probability of success and failure, the expected value, variance, standard deviation and the Bernoulli distribution. It also shows the Bernoulli distribution as histogram and distribution function chart. There are two modes that defines your starting point of the calculation. Either you have certain amounts of successes and failures or a probability of each. Depending on the mode, natural numbers or decimal numbers are supported. The solution is shown step by step. All calculations are stored in the history. The final solution can be shared. [ Contents ] - modes for all important values of a Bernoulli experiment - for mode 1, success and failure must be entered - for mode 2, p or q must be entered - results are calculated and shown in detail - histogram and distribution function graphs - history function to save the input - detailed solution - natural or decimal numbers are supported - no ads! [ Usage ] - there are fields for entering values using a special keyboard - press the check mark button at the bottom right to start the calculation - if values are missing, the corresponding field is highlighted in yellow - if the values are incorrect, the affected field will be highlighted in red - a short message explains why a value is incorrect - the entries in the history can be deleted or sorted - if you select an entry in the history, it will be automatically loaded for the calculation - the whole history can be deleted by pressing a button - solutions can be shared - p and q must be greater than 0 and less than 1
Study Harbors

Study Harbors is a private course workspace for turning source material into an organized plan for learning. PLAN BY COURSE Create separate course workspaces with codes, exam dates, weekly time targets, and color identity. Break the work into learning objectives, then track urgency, priority, progress, and confidence without mixing unrelated classes together. KEEP EVIDENCE WITH THE CLAIM Capture a source title, locator, source type, summary, connection, and tags in one evidence note. Notes stay linked to their course so the context behind an idea remains available when it is time to review or write. PRACTICE RETRIEVAL Build questions from your own material and review them in Recall Studio. Reveal the source-backed answer, grade the effort, and let the on-device interval engine schedule the next review. Upcoming prompts remain visible so the queue is understandable rather than hidden. RUN FOCUSED STUDY BLOCKS Choose a course, name the intended result, and start the built-in focus timer. Afterward, record what changed. Seven-day charts and course allocation show where study time actually went compared with each weekly target. OWN THE RECORD Export a readable study packet, a focus-session CSV, or a complete JSON backup. Restore a backup when needed. Study Harbors requires no account and includes no ads or third-party analytics. Courses, objectives, evidence, recall schedules, and focus sessions stay on the device unless you deliberately share an export. Study Harbors is an organization and learning-practice tool. It does not complete assignments, guarantee outcomes, or replace guidance from an instructor.
