What is sufficient and necessary in discrete math?
A sufficient condition guarantees the truth of another condition, but is not necessary for that other condition to happen. A necessary condition is required for something else to happen, but it does not guarantee that the something else happens.
How do you prove a condition is necessary and sufficient?
A necessary condition is a condition that must be present for an event to occur. A sufficient condition is a condition or set of conditions that will produce the event. A necessary condition must be there, but it alone does not provide sufficient cause for the occurrence of the event.
Is completing all the requirements of your degree program a necessary or sufficient condition for earning your degree?
Completing all of your requirements is both a necessary and sufficient condition for earning your degree. Without completing all requirements, it is impossible to earn a degree, and completing all requirements guarantees earning a degree.
How can I sell myself without a degree?
How to Get the Job When You Don’t Have the Degree to Back It Up
- Think outside the application. If your résumé doesn’t meet the education requirements, think creatively about other ways to distinguish yourself.
- Understand the company’s pain points.
- Demonstrate an ability to learn.
- Build an industry network.
Why college is not necessary for a successful future?
A college degree won’t guarantee you a high-paying job. It won’t even make you a skilled leader with a shot at the corner office. Developing skills such as leadership, decision making, people and resource management takes real practice and experience. These are skills which cannot be acquired in the classroom.
Can a condition be sufficient but not necessary?
A sufficient condition is only one of the means to achieve a particular outcome. This means that there could be other means to achieve the outcome. Therefore, a sufficient condition is not necessary to be fulfilled in order to achieve the desired outcome.
Is $P$ a sufficient or necessary condition for $Q$?
If $p o q$ ($p$ implies $q$), then $p$ is a sufficient condition for $q$. If $ eg p o eg q$ (not $p$ implies not $q$), then $p$ is a necessary condition for $q$. From these two conditions how would you apply necessary but not sufficient? The way I expressed this is: $$ ( eg r \\land eg p) o q$$
What is the difference between sufficient condition and necessary condition?
A sufficient condition is stronger than a necessary condition. If you tell me that you have a red or blue element I can’t say for sure if it is in the purple set, but if you tell me that you have a purple element I now for sure that it is in the red and blue sets.

How do you write a proposition in Discrete Math?
This is from Discrete Mathematics and Its Applications: Let $p, q,$ and $r$ be the propositions: $\\quad p:$ Grizzly bears have been seen in the area. $\\quad q:$ Hiking is safe on the trail. $\\quad r:$ Berries are ripe along the trail. Write these propositions using $p,q,$ and $r$ and logical connectives (including negation):
What is the condition for a×b=b×a?
For the original question, what’s asked is to find a mathematical statement that is true only, and only if A×B=B×A. As for your original question, you’re looking at the conditions for commutativity of the cartesian product. So A×B=B×A if and only if ( A=B, A is empty or B is empty ).
