6 0

Answer:

The number of presentation groups of 3 students that can be selected from a group of 5 students equals 10.

Explanation:

The number of different presenters equals the no of possible combinations of 3 students from a pool of 5 students.

Thus the number of possible combinations equals

\binom{5}{3}=\frac{5!}{(5-3)!\times 3!}=10

Accessibility is the degree to which a product or service is readily available and usable by _____.
spayn [35]

Answer:

Accessibility in the sense considered here refers to the design of products, devices, services, vehicles, or environments so as to be usable by people with disabilities. The concept of accessible design and practice of accessible development ensures both "direct access" (i.e. unassisted) and "indirect access" meaning compatibility with a person's assistive technology (for example, computer screen readers).

Accessibility can be viewed as the "ability to access" and benefit from some system or entity. The concept focuses on enabling access for people with disabilities, or enabling access through the use of assistive technology; however, research and development in accessibility brings benefits to everyone.

Accessibility is not to be confused with usability, which is the extent to which a product (such as a device, service, or environment) can be used by specified users to achieve specified goals with effectiveness, efficiency, convenience satisfaction in a specified context of use.

Accessibility is strongly related to universal design which is the process of creating products that are usable by people with the widest possible range of abilities, operating within the widest possible range of situations. This is about making things accessible to all people (whether they have a disability or not).Explanation:
