Question

Bag B, contains 3 red and 4 black balls while
another bag B2, contains 5 red and 6 black balls.
One ball is drawn at random from one of the
bags and it is found to be red. Find the
probability that it was drawn from B2​

Answer 1

Answer:

0 is your probability because you are perfectly not sure that which colour ball will come and that's why the probability is 1 because either it is possible that black ball can come or either it is possible that red ball can come
