If `A={1,4}` then find `P(A)`

If P(x)= x^4+1 , then find P(2)-P(-2).

P(A)=(1)/(2),P(B)=(3)/(8),P(A nn B)=(1)/(4) then find P((B)/(bar(A)))

if A and B are two events such that P(A)=(1)/(2),P(B)=(1)/(3) and P(A nn B)=(1)/(4) then find P((bar(A))/(B))

Let P(x)=x^(4)+ax^(3)+bx^(2)+cx+d be a polynomial such that P(1)=1,P(2)=8,P(3)=27,P(4)=64 then find P(10)

If E and F are two independent events and P(E)=1/3,P(F)=1/4, then find P(EuuF) .

If qr : pr : pq = 1:4:7," then find " p/(qr) : q/(pr) .

If A and B are two events such P(A)=1/2,P(B)=1/3and P(AcapB)=1/4 ,then find (i) P(A/B). (ii) P(B/A). (iii) P(A'/B). (iv) P(A'/B').

7balls (distinct) are to be placed in 7 boxes (distinct) and 4 of the balls can not fit into 2 small boxes.The number of ways of arranging one ball in each of the boxes is X .Let P be the probability of selected divisor in the list of divisors of X is in the Form of 4n+1 ,then find 6P (where n in N)
