A die has two faces each with number '1', three faces each with number '2' and one face with number '3'. If die is rolled once, determine  i. P(2) ii. P(1 or 3) iii. P(not 3)

There are two die A and B both having six faces. Die A has three faces marked with 1 , two faces marked with 2 , and one face marked with 3 . Die B has one face marked with 1 , two faces marked with 2 , and three faces marked with 3 . Both dices are thrown randomly once. If E be the event of getting sum of the numbers appearing on top faces equal to x and let P(E) be the probability of event E , then P(E) is maximum when x equal to
