00:01 Let's have a look at the question.

00:03 So the question state construct a truth table for the following statement form.

00:08 So we have p implies that q implies r and then we have if and only if here we have p and q together imply.

00:33 So here we have to construct a truth table for this statement.

00:36 So here we will have a table for p q and r.

00:41 Let us draw a line here and here we have for q for r then we have for representing p and q together.

00:52 Then we have for q implies r.

00:55 Next we will have for p implies q which implies r.

01:01 Then next we have p and q together they imply r and then we have for whole p implies q implies r and this whole implies if and only if we have p and q which together implies to r.

01:25 Now here we will take the first case here false false false false.

01:31 Then here we have true true true and true.

01:35 Next we will have false false then true true false false and true true.

01:43 Next we will have false true false true false true false and true.

01:50 So these are the entries for p q and r.

01:54 Now p and q in false and false will be false then again here false and false will give us false.

02:02 Then we have false and true will give us false again false and true will give false.

02:09 Then true and false also gives us false then true and false again gives false.

02:14 Now here we have true and true will give us true and at last true and true again will give true.

02:20 Now let us construct here also lines to make this table clear.

02:26 Now q implies r.

02:28 Here q implies r will give false and false.
