Binomial Probability Distribution for Defective Bulbs in 4 Bernoulli Trials

[@hisokaamorou4211]

Thank you sir very very much, i was stuck in the question similar as this and had no idea how to move my pen to solve that, finally youtube led me to you! I'm very grateful for this video and your teaching!

Again, thanks for your help. I Wish you were my Prob teacher. Well, you are already. Thank You Sir.

Sir why are using Binomial distribution when bulbs are replaced???

[@MathematicsTutor]

Thanks. Each trial becomes independent trial with replacement. The probability is independent of the previous result and it remains constant all throughout . That is important for using binomial distribution. Hope that helps. Thanks

So what's happened when no replacement

p(x=1) isn’t correct.
