Let `S = {E_1, E_2,……..E_8}` be a sample space of a random experiment such that `P(E_n) = n/36` for every n = 1, 2,….,8. Then the number of element in the set `{AsubeS : P (A) ge 4/5}` is ___________.

If S be the sample space and E be the event then P(E)=

Suppose P{S) denote the power set of the set S. Let A = {1}. If the number of elements in the P(P(P(P(A)))) is 4n then n =__

Let A, B,C be any three events in a sample space of a random experiment. Let the events E_(1)= exactly one of A,B occurs, E_(2)= exactly one of B ,c occurs, E_(3)= exactly one of c ,A occurs, E_(4)= all of A,B ,c occurs, E_(5)= atleast one of A,B, c occurs P(E_(1))=P(E_(2))=P(E_(3))=(1)/(3),P(E_(4))=1/9,P(E_(5))=

Let E_(1) and E_(2) are the two independent events such that P(E_(1))=0.35 and P(E_(1) uu E_(2))=0.60 , find P(E_(2)) .

If A={p:p=((n+2)(2n^(5)+3n^(4)+4n^(3)+5n^(2)+6))/(n^(2)+2n), n p in Z^(+)} then the number of elements in the set A, is

The least value of n such that (n-2)x^(2)+8x+n+4>0, where n e N ,

Let E1 and E2 are two independent events such that P(E1) = 0.3 and P(E2)= 0.6. Find the value of: (i) P(E1nn E2) (ii) P(E1 uu E2) (iii) P(E1//E2)(iv) P(E2//E1)

Suppose E_1 and E_2 are two events of a sample space such that P(E_1)=1/2, P(E_2|E_1)=1/2, P(E_1|E_2)=1/4 then P(E'_2) = _____

Let S be the sample space of the random experiment of throwing simultaneously two unbiased dice with six faces (numbered 1 to 6 ) and let E_(k)={(a,b)in S:ab=k} for k>=1 If p_(k)=p(E_(k)) for k>=1 then correct among the following,is (Eamcet 2008)
