Yes, i only read ncert previous year and got 94 marks in maths without consulting refrence book. But only some condition required :- 1. You should solve [NEARLY] all questions 2. But you must have to solve [EACH AND EVERY] examples. 3. You must have deep knowledge of topic. (*ncert is good enough to fix issues) 4. Do miscellaneous exercise for proper revision of chapter. (IT IS A FACT THAT 55% of question are comes from miscellaneous which means 44 marks out of 80, so please please refer those which SURELY raise the bar) *reference from www.cbse.nic So keep that in mind you all have 24 hour left....... And all the best for your exams and again if u think u wouldn't have enough time to get satisfactory marks. So please only solve miscellaneous exercises

These sets must be given for a die.. P(E) =3/6 P(F) = 2/6 P(G) = 4/6 P ((EUF)/G) = P(EUFandG )/P(G) = 3/6 / 4/6 = 3/4 Similarly P((EandF)/G) =P(EandFandG)/P(G) = 1/6 / 4/6 = 1/4

ANSWER

I am writing difficult question so be careful while writing answer First of all a trasitive relation is when, If a Relation in any arbitary set A, if (a, b) € R and (b, c) € R implies that (a, c) € R, for all (a, b, c) € A Let consider a set A = {1,2,3} and a Relation R defined on set A as follow: R = {(1,1), (1,2), (2,1)} Let assume that a is 1 b is 2 c is 1 Now. (a, b) € R means (1,2) € R And. (b, c) € R means (2,1) € R Implies (a, c) € R means (1,1) € R So this must be transitive relation, BUT IT IS NOT. WHY? *I have no time so please answer the question as soon as possible if u can

Khushi Varshney 5 years, 6 months ago

YES ,ADVAIT IT'S NOT TRANSITIVE...It's bcoz you have to check transitivity from all the angles...I mean to say that you need not to fix the values of a,b,c as 1,2,1 or anything else..You should also check that (2,1)and (1,2) are here in R but not (2,2).that's why it's not transitive... HOPING,NOW YOU COULD UNDERSTAND WELL....

Advait Gaur 5 years, 6 months ago

It is easy. Cos(90) = l = 0 Cos(135) = m = -1/√2 Cos(45) = n = 1/√2 Where l, m, n are direction cosines So direction cosines are as follow 0, -1/√2, 1/√2
