to sum up: Biconditional operator p q it's a conjunction between p->q & q->p the statement is true if and only if both of p and q are equivalent (both are true or false) pq means p is necessary and sufficient for q and vice versa.. necessary ( p=false then q=false for sure) sufficient ( p=true then q=true for sure)

Solution of HW Problems: 1. You will be informed if and only if you read newspaper everyday. 2. It rains if and only if it is a weekend day. 3. The trains run late if and only if I take it. 4. You can get an A in this course if and only if you learn how to solve discrete mathematics problems. Thank You:)

1. Everyday you read the newspaper if and only if you will be informed and conversely. 2. It rains on a weekned day if and only if a weekend. 3. The train runs late if and only if I take it those days. 4. For this one, I believe the statement is already written in the form "p if and only if q" since " it is necessary and sufficient " means the same just different working.

Can we consider biconditional operator as a XNOR gate?I mean the turth table are the same.

@atulv46 5 лет назад

Ur right

@ha06_0 Месяц назад

we can simply say that it is necessary for both propositions p and q to be same. They're necessary and sufficient for each other, else the compound proposition will be false!

@jayprakashthakur1629 Год назад

Can anybody explain how p only if q means if p then q??? because it sounds like p happen only if q happen that means we are applying condition q on p. so it means if q then p!!!

@IsaAbuhuseina Год назад

Can anyone please answer this question for me? I'm really confused! Q. For an implication "p implies q", if "q" becomes hypothesis and "p" becomes conclusion, then it is ____ of the given implication "p implies q".

@rajeshprajapati6662 Год назад

Answer should be "Converse" because P->Q [Implication which is given] then it is said that q is hypothesis and p is conclusion. So, it becomes Q->P. Right ? So, Q->P is converse of of Implication P->Q. Isn't that so ?

Please do correct me if im wrong,Thankyou! 1.Not bi conditional 2.Bi conditional 3.Bi conditional 4.Bi conditional

@vasubhatt6160 5 лет назад

No it's not. Because it also says conversely ! That means reverse is also true. And if you see the problem is not to find which are bi conditional prepositions but it's to convert them into bi conditional .

@@jayxcoder the truth table of contrapositive of p->q is equal to truth table of p->q . According to you,you can write there contrapositive of p->q. But it is wrong. You should try to indentify the p and q first .Then you fix the problem.
