Answer 1

ok u have to find seperately two probibailities, one for Urn1 red ball and 2nd for Urn2 red ball.. then u you have ti take there AND and that will be ur answer

Answer 2

did u get it ?

Answer 3

idk how?

Answer 4

ok

Answer 5

well first we find the Probibality for Urn1 red ball
Urn contains 8 green and 12 red total balls are 12+8=20
the so when we pick one ball from it the chance of being red is its probibality it will be 12/20 got it till now its for Urn1

Answer 6

P(red for urn1)= 12/20 = 3/5
P(red for urn2)= 8/13
P(red AND red)= (3/5)x(8/13)
= 24/65
