- Neelam has offered physics , chemistry and mathematic sin class XII. She estimates that her probabilities of receiving a grade A in these course are 0.2 , 0.3 and 0.9 respectively . Fins the probability that neelam receives : exactly 2A grades
- What are independent events?
- If A and B are independent events, such that P(A) = _{}, P(B) = _{}, then find _{}.
- If A and B are independent events, such that _{}= 0.8, P(B) = 0.6, then find the probability of occurrence of A.
