Assuming that probility is your failed attempt to spell probability, the activity is repeated trials whose outcomes are independent, identically distributed (iid) variables.
PERT is Program Evaluation and Review Technique which is used to identify the most realistic estimate/duration of an activity in a project. It uses the following formula PERT = (P+O+4M)/6 Where P is Pessimistic estimate O is Optimistic estimate M is Most likely estimate

This model is used to estimate economic effects that an initial change in economic activity has on a regional economy.
Counting Principle is used to find the number of possible outcomes. It states that if an event has m possible outcomes and another independent event has n possible outcomes, then there are mn possible outcomes for the two events together.
For patients prescribed bed rest, the activity factor used to estimate energy requirements is typically 1.2. This reflects the minimal energy expenditure associated with being confined to bed and limited physical movement. It is important to adjust the patient's energy intake based on their specific needs and any changes in their condition.
It is used when repeated trials are carried out , in which there are only two outcomes (success and failure) and the probability of success is a constant and is independent of the outcomes in other trials.
If the question is about 4 successful outcomes out of 16 trials, when the probability of success in any single trial is 0.20 and independent of the outcomes of other trials, then the answer is, yes, the binomial experiment can be used.

Tree diagrams are used in math to see how many possible outcomes there are. The sample space of a tree diagram shows you how many possible outcomes there are.
An estimate is based on available data, experience, and assumptions about a particular situation or variable. It often considers historical trends, expert opinions, and statistical models to project future outcomes. The accuracy of an estimate can be influenced by the quality of the underlying information and the methods used in its calculation. Ultimately, estimates serve as informed approximations rather than precise values.
