My doubt is --How can we solve this question by combination ?
The explanation given is
- 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.
