Selects, we are given a question that let's say that i construct, construct an indirect truth table for an argument, okay? in the end, the table shows t under the main operator for every premise and f under the main operator for the fun user.
00:16
This would show this argument to be rv belongs to here minus t by s and t f f, okay.
00:24
Now we are given four options, invalid, false, valid and true.
00:27
So first of all, we are supposed to know that an argument, an argument is said to be valid only when all the premises are true and also the conclusion is true.
00:37
So we can just write here an argument, okay? an argument is valid if all the premises are true, all the premises are true and also the conclusion is true.
00:58
Also the conclusion is true okay otherwise we can see that an argument is said to be invalid if all the premises are true and conclusion is false and an argument is invalid if all the premises all the premises are true and conclusion is false conclusion is false okay now here we can say that according to the given problem we can say that it is given that it is said that all the premises are true but conclusion is false okay as we can see see here all the premises all the premises are true okay but conclusions are false.

Conclusion are false...
