:

Given P (A) = 0.60 P (B) = 0.40 P (A /B) = 0.24
FIND P (ABU) ?

Sol:

             P(A/B)={P(A intersection B)}/ P(B)

Q6 = if P (A intersection B) = 2/15
p(A) = 34/80
P(B) = 4/10
are they independent?

Ans :whenA and B are independent then
    P(A intersection B)=P(A)+P(B)
solve kar k check kar lo agar ans equal aaata ha to independent ho ga

 

Q2=  IF P(A^B)=... and P(A)=.. P(B)=..
are A and B independent?

 Ans :
   If A and B are inependent then P(A/B)=P(A) hota ha so the answer of this question is false
