ICSE − Q & A

Proofs of theorems are not in syllabus, right? 
I just want to confirm.

Our teacher told us to steer clear of the Ogive question since there's a large possibility of human-error (the hand made graph). Thoughts?

Also, guys don't forget to write theorems, formulae,etc on the right hand side, lest should lose a mark! And 99 hurts..

Is sample space compulsory in every probability question?

In triangle PQR,M is the midpoint of QR and N is the midpoint of PM. If QN when produced meets PR at S,then find the ratio of area of triangle PQS and are of triangle QSR.
This is a crazy question. Could someone help me with this?

Please prove it!!!

Okay so just rechecking. Say we get a squareroot of a prime no. And it can't be simplified. We can use the log book to find the squareroot right?
Also Can y'all name the chaps where even if the squareroot is coming as the answer, we gotta show the working?

Guys question is that there are 2 boys....
Both were born in 2000...
What is probability of:

(I)Birthday on same day

So the total outcomes will be 366² no? And favourable outcomea will be 366...

Thus P(same day)=366/366² = 1/366
