Homework Statement In how many ways can 12 balls be arranged into 4 different rows with each row having at least one ball (a) if the balls are identical? (b) if there are 6 identical red balls and 6 identical blue balls? Homework EquationsThe Attempt at a Solution a) Put 4 balls in each row...

Hi so the ans is. There exists a rational number r, Where all integer a and all integer b such that r != a/b May i know what is "such that' converted to? For my case i tot it means "then"

my attempt. Let P = At least one a and at least one b Let Q = r=a/b Hence the proposition is simplified to, For all r where P Then Q Negation: Not all r where P Then Q = Atleast one R When Not(P Then Q) Not(P Then Q) = P And Not Q Hence Atleast one R When Not(P Then Q) = Atleast one R When...

Wait is it correct to do this. 1) Draw Kmap with don't cares 2) Obtain SOP 3) Negate SOP Method 2 1)Change all the 1s to zeroes and zeroes to 1s. Keep the Dont cares the same 2)Draw Kmap 3)Obtain SOP Are these 2 methods the same?

Homework Statement Homework EquationsThe Attempt at a Solution The answer is not given. What i did was i drew the kmap and used minterms 0,2,8,11 and dontcares 3 and 10. So is the complement of it 1, 4, 5, 6, 7, 9, 12 13, 14, 15 ? So issit non of the above?

As in is there a boolean algebra way? Yea i know it can be done in kmap. Just curious

ab'c + a'b + bc' + abc = ac + a'b + bc' (How to further reduce this?) Kmap gives B + AC

Except when all zeroes right?

Homework Statement Homework EquationsThe Attempt at a Solution As long as A = 1, its true, So options (A) and (C) are wrong. My ans is (E). Right?[/B]

yeayea! thank you man solved it lol. I was thinking it too complicatedly.

So must i like do the excess-3 table and compare ab < cd values

Ok my formula was Si = Xi XOR Yi XOR C That was wrong. Should be Ci. hmmmm I need clue bro lol

My working: S3 = A S2 = B S1 = C' S0 = D' F = Sum-Minterm(0, 1, 2, 4, 5, 8) (Basically i find when is X smaller then Y) Used Kmap to arrive at A'C' + B'C'D' + A'B'D' Am i correct?

Thanks!

I need to find the total number of Prime Implicants in a Kmap Is the one in red also a prime implicant?
