Math Problem Statement
На рисунке изображена диаграмма Эйлера некоторого случайного эксперимента. Найдите условную вероятность события B при условии события A.
Solution
To find the conditional probability , we use the formula:
From the Euler diagram in the image:
- (the intersection of events A and B)
- (the total probability of event A)
Now, calculating:
Final Answer:
