Probability # 8 | When balls are drawn from the bag with replacement or without replacement

[@tamannakhatri9509]

Sir, I learnt maths from you in class 12th . Due to some circumstances I couldn't prepare for IIT. . Currently I'm preparing for SSC CGL and SSC added probability in syllabus. It has been three years since but still you and your awesome teaching style in my memory. After watching your lecture today again I am overwhelmed with emotions. You not only taught me maths but also the moral values I actually needed throughout the life. Thank you so much sir 😊😊

[@pranavkrishna539]

just wow sir , concept samaj agaya

[@Wtf_Ahmad]

Thanks a lot sir, i was struggling in this topic ❤️ ❤️

[@shipramishra7498]

Sir please next 1-2 videos probability pe hi kijiye, ismein aur bahut saare question ban sakte hain aur RD Sharma ke kuch questions mein thhodi dikkat ho rahi hai And thank you, sir, for picking up Probabilty again.

[@ashishkushwaha8837]

You are amazing sir ❤️ I am studying at 1:20 am, but during your video I didn't slept yet.

Thanks a lot sir is topic ko itna aasan banane ke liyee

[@ashokkumaryadav525]

Sir at 43:50 if we are removing white ball from bag 1 then it must have one ball less and it's probability must be 1/4... Kindly tell whether I am correct or not.

[@RKGuptaClasses]

Before romoving there are 2 white and 3 black balls.... After removing 1 white ball there will be remaining 1 white and 3 black balls.... but we have to find the probability before removing any ball.... So, probabaility of removing white ball (in the starting) = 2/5

Sirr aapko aapko bohot bohot thank you aapki wajah se mujhe ye chap. Ache se smjh aa gaya 👌👌👌👌👌👌👌👌❤️❤️❤️❤️

[@debashish1096]

being a competitive student of bank exams i found this video as bread and butter for my probability concepts... need such type of problems of with and without replacement videos with high level. if possible, please make a video on these problems sir...awaiting your response

[@youtubeaccount2655]

Hi, at 40:14 , alternative color without replacement, I think WBWB should not be add to BWBW, as both have same answer and during combination, order is not important. Kindly correct me if I'm wrong. Thanks.

[@RKGuptaClasses]

There is no effect whether both answer are same or different. If we may find the total cases then BWBW and WBWB and many other non alternate cases are involved... so we have to sum the BWBW and WBWB as favourable cases to find the answer.....

[@jyotirmoymazumdar3189]

Sir selected at random and selected one by one mai difference kiya he?

[@RKGuptaClasses]

Selected one by one means which came first and second and so on.... But this is not possible in at random case...

[@jyotirmoymazumdar3189]

Random means at a same time we select the balls... But sir if we have to take two balls at a random and after taking 1st one this will not be replaced then how we calculate probability both ball will different colors???

[@jyotirmoymazumdar3189]

And sir... After taking 1st ball there will be any changes or reduces from total cases ??? Bcz 1st ball will not replaced but it will selected at random....

[@RKGuptaClasses]

Exactly, this is done.... means the total cases is reduced because the ball is not replaced after the selection....

[@RKGuptaClasses]

In the last or second last video of probability, i have discussed it....

[@bharatsejudo1596]

Sir I am no getting this Please help me Three bags of the same type have the following number of balls : Bag 1 : 2 black and 1 whiteBag 2 : 1 black and 2 whiteBag 3 : 2 black and 2 whiteRandomly one bag is selected and one ball is drawn, it turns out to be white. What is the probability of drawing a white ball again when the first one is not replaced ?

[@RKGuptaClasses]

1/3 (drawing white ball by total probability theorem assuming that the white ball was previously drawn from bag 1) + 1/3 (drawing white ball by total probability theorem assuming that the white ball was previously drawn from bag 2) + 1/3 (drawing white ball by total probability theorem assuming that the white ball was previously drawn from bag 3)

A bag contains 4 red and 6 white balls. Two drawn are made without replacement, what is the probability that the balls are- 1. Red 2. White Please solve this question sir?

[@RKGuptaClasses]

4/10 x 6/9

[@rehatkaur7675]

The ans for 1. Red will be (4/10)*(3/9) And for 2. White is (6/10)*(5/9) Sir I think you have misunderstood the ques It is not 1 Red and 2 white as only 2 balls are drawn and there are 2 questions

Sir i have a problem for which I need a solution. Kindly help. consider 2 black, 9 white and 3 pink balls. if a pencil is drawn at random and replaced and this process is done 2 more times then what is the prob of drawing 2 black and 1 pink. My proposed solution and as per my mentor - (2/14 * 2/14 * 3*14) * (3!/2!) However many websites ignore the - (3!/2!) (3!/2!) - It is taken as a sequence of choosing the balls is not given. I Can take BBP, BPB, PBB.. and I should consider probability for all 3 cases.. Pls confirm if my understanding is correct.

[@RKGuptaClasses]

(2/14 * 2/14 * 3/14) * 3 correct hai...... But if the first time Black, second time black and third time pink then its answer will be (2/14 * 2/14 * 3/14) only

[@wargokul]

@@RKGuptaClasses Ok Sir..thanks ...But how to approach agar question me sirf yahi diya hai ki 3 balls are taken wit replacement...should we consider 1 arrangement or multiple arrangement.

[@RKGuptaClasses]

In this case multiple arrangement lena hoga
