Merry Christmas and Happy New Year in advance to you all

jmoore: You need vitamin A for clear vision.

hahahahahahahahahahahahaha

hmmmm. It's like this man is now a supporter of APC. I'm beginning to see APC as corrupt as PDP cos all the aggrieved PDP members are now joining APC.
Hmmmm. Politics!

hmmmm.

The content of this news doesn't corroborate the heading. Lecturers to teach from home or to send assignments to students from home

A good development any way!

'The two are correct and formal' says my 'Invisible teacher'.

@ smurfy,someone has solved it earlier gan. Bring more. I will also get some for you guys when I get home.

smurfy: So you spent a million years just to go to mars, buy land and to return?

Well, let's say you spent x years in mars arguing with omo onile and stuff. That means you spent the remaining (10^6 - x) years travelling through space? It further confirms that your journey to/from Mars took approximately 0.5(10^6 - x) years!

LMAO
This is called a mathematical crinkum-crankum.

I hope you've seen the solution now. I actually have not gotten home now. I just did it in the bus.

Now,@smurfy.

By considering each of the five position... We have P,Q,R,S,T. And if the letter R must be to the right of S,this can not be possible if S is the last letter,hence S can only occupy any of the first four positions. That can be done in 4 ways. Then the remaining for letters can then be permuted round it in 4! ways. That means the whole arrangement can be done in 4*24 ways= 96 ways.

But the question says R must be to the right of S. Then let's consider each of the four positions which can be occupied by S and see how many of it will have R being at the left side of S (which obviously would be against the condition).
Now,if S is the first letter,R will always be to the right of S. That one is settled.
If S is at the second position,R may be at the first(which is against the rule also),so this way,the other three letters can be permutted in 3! ways = 6 ways.
If S is at the third position,R may be at the 1st or 2nd position. In each case,the other three letters can be arranged in 6 ways also. Altogether making 12 ways.
And finally,if S is at the fourth position,R can be at the 1st,2nd or 3rd position. In each case,the remaining 3 letters can be arranged in 6 ways. Altogether making 18 ways.

Please note that I only considered cases where R may be to the left of S as against the condition given.
If you add up all the different arrangements that can be against the rule(i.e where R is at the left side of S),you get 6+12+18 = 36 arrangements.

Therefore out of the 96 ways gotten earlier,only (96-36) ways will always have R at the right side of S(as stated in the question). Hence,answer equals 60 ways.

So,where is my recharge card

smurfy: Which condition are you referring to? If you're referring to the condition in the original question, then I can assure you that the answer provided is as correct as they get. It's 60 and not 90.

And, where have you been all these million years?

Oga mi,I just go buy land for Mars ni o. You know say heaven and earth go soon pass away.

As per the question,I will take a better look at it when I get home in less than two hours' time.

smurfy: In how many different ways can the letters P, Q, R, S, T
be arranged if the letter R must
be to the right of the letter S?

If the letter R must be to the right of S,it means S can occupy only any of the first four positions. That can be done in four ways. The remaining four letters could be arranged in 4! ways which is 24,which means everything could be done in 24*4 ways,which is 96. But out of this 96 ways,3+2+1 of them may have S to the right of R which is contrary to the condition stated.

Hence,going by the condition,it can be done in (96-6)ways which is 90 ways.

What's the use of resumption without lecturers

Jona should do the needful abeg!

Resumption without lectures! What's the use

Jona,abeg give these people what they want and let lectures start fully!

Iyen emi o. Lenu e.

Well,just bring back the debate sha;let me contribute! That's all.

I no go gree o!

I laff so tey I fall from untop Glo mast!!

Oluwatola5: Team Maths FC, cant you guys just accept the defeat in good faith Team English FC won it nau, so please you guys should take it in the spirit of sportmanship so we dont derail the thread.


All will be well in the next life(if such exists).......

When did that take place

Happy new month to you all! Please is there anyone here who stays close to Ife? I need your assistance urgently!
