Answer 1

Since, the question is incomplete and unclear, we consider this question.

There are two bags A and B. Bag A contains 5 red balls and 3 blue balls. Bag B contains

3 red and 5 blue balls. A fair die is rolled, if 3 or 5 turns up a ball is drawn from the bag

A else the ball is drawn from the bag B. Find the probability that a blue ball is drawn.

Solution:

P(Blue ball) = P(Blue ball from first bag) + P(Blue ball from second bag)

$=\dfrac26\times \dfrac38+\dfrac46\times \dfrac58 \\=\dfrac18+\dfrac5{12} \\=\dfrac{13}{24}$
