    In this video, I have discussed the basic concept of permutatin and combination and then started directly with probability.
    Ye alag se UA-cam ke liye nahi shoot ki thi. Live Class thi app pe, vo hi upload ki hai, so speed thoda badhake dekh sakte ho agar pehle padha huwa hai.

      Sir, at 58:42 minutes Probability of(Head and Blue), i think it applies the idea of Conditional probability and Multiplication Theorem of Probability which states that P(A & B) = P(A) * P(B/A) where P(B/A) represents the conditional probability of happening of B, given that A has already happened. So, i think the answer would be P(HB)=P(H)*P(B/H) = (1/2)*(3/7) = 3/14. I am not sure. Please correct me if i am wrong.

      Sir at 6:30 in the question, only 1 dice is rolled 4 times, so i think the possible outcome will be 24, the answer you gave will be true if 4 dices are rolled simultaneously. Please correct me if I m wrong.
