[@creat7]

Thank you alot I appreciate this video it had taken me alot of time to understand but when you worked it out I understood

Thank you so much! I am cramming before my final tomorrow!

[@hiiam_sami]

yes there is , first u need to assume all ur premesis are true then after that u can find the truth value of each then u gonna go to the conclusion and insert the truth value that u got . if it yield true its valid if it yields false then its invalid.

Is there a case that these arguments can be valid? Thankyouu

Sir

[@baldaiomir]

what if i have for example 5 variables? do i need to write all 32 rows? is there a way to solve this without the truth table?

Check it is valid or invalid?? If the two sides of the triangle are equal then opposite angles are not equal .Therefore opposite angles are not equal

[@hiiam_sami]

its invalid

That was really helpful, thanks to u!! but I couldn't understand neither the falsity of the 3rd row (the 1st example)🤔nor the whole second example especially with the final answer column. can someone plz explain that for me 😵

[@keiramae6573]

for the first example p, the third row of p is false, hence the conclusion will also be false, invalidating the entire argument. its same for the second example where the last row of g is false, so the conclusion g will also be false, invalidating the entire argument. for truth tables, if there is one row that is false, it invalidates everything even though there are rows wherein the conclusion is true. everything has to be true so that the entire argument can be valid. hope this helps!!

[@mohammedzainkhazi7667]

In b) r- -> ~g should be False

[@levskt6552]

It should be true.. A premise should be assumed to be true

[@pusatbahasa5694]

Ga bisa bahasa engress

[@artursowinski9402]

The second argument could be expressed like this g=> not r and not r therfore g then you could say that the structure of the argument is the same as in a hence argument b is invalid
