To use the program service routines, the user's program makes requests to the operating system through the application programming interface (API).
API <span><span>is defined interfaces</span> that specifies how software components interact with each other and </span><span>between an enterprise and applications that use its assets.</span>
Answer:
The probability that at least one 5 will appear in 4 rolls of die equals 
Explanation:
The given question can be solved by Bernoulli's trails which states that
If probablity of success of an event is 'p' then the probability that the event occurs at least once in 'n' successive trails equals

Since in our case the probability of getting 5 on roll of a die equals 1/6 thus we have p = 1/6
Applying the values in the given equation the probability of success in 4 rolls of die is thus given by

Explanation:
Conceptual design refers to the early phase of the design process, whereby the outlines of function are articulated. The conceptual design consist of the design of processes, interactions, and strategies. It is the first stage in the database design process.
The output of the conceptual design process describes the main data entities, and constraints of a particular problem domain. To simplify the conceptual design, most higher-order relationships are decomposed into appropriate equivalent binary relationships whenever possible.
