Question 1019461
Two distinct dice A and B are rolled. What is the probability of each of the following events?
(i) At least one 4 appears. 11/36
(ii) Just one 4 appears.   10/36
(iii) The sum of the face values is 7.  6/36
(iv) One of the values is 3 and the sum of the two values is 5. 2/36
(v) One of the values is 3 or the sum of the two values is 5.  still 2/36

I suggest you draw a grid, 6 across, 6 down, across the top, show the numbers 1-6 and do the same down the side. Then show the pairs that result, all 36 combinations. Only then will my answer make sense.
