If `(a)/(b)=(7)/(4)` then find `(b+a)/(b-a)`

If P(not A) = 0.7, P(B) = 0.7 and P((B)/(A)) = 0. 5 then find P ((A)/(B)) and P (A cup B)

If AxxB={(a,2),(b,4),(a,6),(b,2),(b,6),(a,4)} , then find A and B.

If P(A)7/(13),P(B)=9/(13) and P(AnnB)=4/(13), find P(A/B)dot

If P(A)7/(13),P(B)=9/(13) and P(AnnB)=4/(13), find P(A/B)dot

If A and B are independent events with P(A)=3/7 and P(B)=2/5 then find P(A' nn B')

Evaluate : (ii) ((4)/(7) a+ (3)/(4) b) ((4)/(7) a - (3)/(4) b)

if A=[{:(3,-2),(7,1):}]and B=[{:(2,3),(-1,4):}], then find (i) A+B (ii) A-2B

The value of int_a^b (x-a)^3(b-x)^4dx is (a) ((b-a)^4)/(6^4) (b) ((b-a)^8)/(280) (c) ((b-a)^7)/(7^3) (d) none of these

If a-b= 4 and a+b= 6 , find: ab

If a +b= 7 and ab= 10 , find a-b
