So in this question we are given these three english sentences here, p -e -s, and we are asked to translate each of these statements into logical expression using the propositional variables, and then negate the entire logic expression using the morgan's law.
00:26
So first let's translate this english statement into a logical expression using the propositional variables.
00:37
Pes.
00:38
So the first one here, the applicant has written permission from his parents and n is at least 16 years old.
00:53
So the applicant has written permission from his parents is p.
00:58
Here so p and is at least 16 years old which is s the applicant is at least 16 years old so this is our statement in a logical form and then we are asked to negate this statement here using the morgan's law so using the morgan's law we can negate this statement and then this statement becomes the negate this statement of p is just not p and the negation of n is or negation of s is not s.
01:41
So this is the negation of this statement here, this original statement.
01:45
And then we are asked to write the statement, this logical statement here, into plain english.
01:57
So now, now p is, as you can see here, p is the applicant has written permission from his parents...
