Bag A contains 6 Green and 8 Red balls and bag B contains 9 Green and 5 Red balls. A card is drawn at random from a well shuffled pack of 52 playing cards. If it is a spade, two balls are drawn at random from bag A, otherwise two balls are drawn at random from bag B. If the two balls drawn are found to be of the same colour, then the probability that they are drawn from bag A is Sir ee type of questions kuda explain cheyandi sir
Probability for a spade to be drawn=13/52=1/4 Two 🏀 are selected and must be of same colour. No of ways of choosing 2 balls from bag A=6c2(red) +8c2(green)/14c2 Our favourite outcome must be a spade drawn hence, favourible outcomes= 1/4(6c2+8c2) /14c2 Now all possible outcomes= Spade + non spade outcomes. Wk prob of spade outcomes Non spade= diamond, heart, club. =3/4 and now ball is drawn from Bag B so, 2 balls of same colour are choosen as 9c2(green) +5c2(red) Probability of non spade outcomes=3/4(9c2+5c2) /14c2 Total probability=total favourablr outcomes/total possible outcomes =1/4(6c2+8c2) /14c2/1/4(6c2+8c2) +3/4(9c2+5c2) 14c2= Final ans= 43/181

Sir at 28:13 u just considered 2,3,5,7..but a diamond card has 13 cards in which 11 and 13 also a prime number or else u haven't took the face cards sir 🤔
Diamond card contains (13) that 13 cards are king, queen, jack, ace, and it contains number from 2-10.. so there is no term of taking 11 or 13 as you asked..
Please make all chapters most important pyqs

Sir ee type of questions kuda explain cheyandi sir
Probability for a spade to be drawn=13/52=1/4
Two 🏀 are selected and must be of same colour. No of ways of choosing 2 balls from bag A=6c2(red) +8c2(green)/14c2
Our favourite outcome must be a spade drawn hence, favourible outcomes=
1/4(6c2+8c2) /14c2
Now all possible outcomes= Spade + non spade outcomes. Wk prob of spade outcomes
Non spade= diamond, heart, club.
=3/4 and now ball is drawn from Bag B so, 2 balls of same colour are choosen
as 9c2(green) +5c2(red)
Probability of non spade outcomes=3/4(9c2+5c2) /14c2
Total probability=total favourablr outcomes/total possible outcomes
=1/4(6c2+8c2) /14c2/1/4(6c2+8c2) +3/4(9c2+5c2) 14c2=
Final ans= 43/181
At 30:00 the answer will be 94/663
