Probability_Balls_problem
There are $2$ boxes, $1$ containing $10$ red balls and the other containing $10$ green balls. You are allowed to move the balls between the boxes so that when you choose a box at random and a ball at random from the chosen box, the probability of getting a red ball is maximized. What is the maximized Probability?

Probability Problem
Suppose we have 2 bags. Bag 1 contains 3 red and 7 green balls. Bag 2 contains 4 red and 8 green balls. A person tosses a coin and if it is heads goes to bag 1 and draws a ball. If it is tails, he goes to bag 2 and draws a ball. Given that the ball draw is red, then what is probability that it came from bag 1? $0.317$ or $0.4737 \ ?$

Questions Doubt
Doubt: 1) If its asked that what address does $PC$ hold after execution of $HALT$ what it should be? 2) If the question does not clue about access mechanism for cache what mechanism to hold $hierarchical$ or $simultaneous$ ... ? 8) Processor access $TLB$ first or $Cache$? if its mentioned both then whose access considered first? Thank you for your time!

Self_doubt
1) If a binary relation itself is transitive , then the transitive closure is same as that relation $True \ OR \ False?$ 2)If a node in BST has $2$ children,then its inorder successor has no left child and similarly its inorder predecessor has no right child  $True \ OR \ False?$ 3)Thrashing slow down the process execution time by several magnitute  $True \ OR \ False?$
