Hello students in this question let a be the event that either 3 or 4 is rolled first followed by an even number.
00:12
So here when a has 4, 6 4, 4 3, 2 4, 2 3, 6 and 3, 4 that means 6 elements.
00:34
So here probability of a equal to number of elements in a divided by number of elements in sample space.
00:42
So that is equal to 6 divided by 48 and next question that is p that is let b be the event that sum of 2 rolls is at most 7 that means p has 4, 1 1, 2 3, 1 2, 1 1, 5 1, 3 0, 1 2, 2, 3, 1, 1, 2, 4, 4, 3, 1, 4, 3, 3, 5, 1, 3, 4, 3, 2, 4, 2, 0, 3, 2, 2, 5, 0, 2, 0, 0, 6, 6, 1, 0, 4, 0, 5, 1, 6 and 5, 2...
