zubair_slipknot:

(i) P=1/3
    q=3/8
    r=6/8
    s=2/8
but i wanted to verify it whether its correct or not...the (b) part i have no idea how to do

zubair_slipknot:
(ii) 5/12
(iii) 5/18

zubair_slipknot:
any help in october novmeber 2008 paper...tell me...i will try my best to help

Ghost Of Highbury:
okk.,
your a)i) answers are correct...By the way...r=6/8...=3/4 (lowest terms, always)
  a)ii) is correct but a)iii) ...the answer is 2/3

a)iii) A white ball can pop up from bag A OR bag b
   the probability of white ball from bag A is (2/3 * 5/8)
   the probability of white ball from Bag B is (1/3*3/4)
soo u add them up because its OR....i.e (2/3*5/8)+(1/3*3/4)...= 5/12 + 1/4 = 2/3
 :) :) hope u understood
