This is a definition problem, not a calculation problem.
Write down the entire distribution.
Row and Column Titles are 1, 2, 3, 4, 5, 6
Add them up in the interior, making 2, 3, 3, ..., 12
Now answer the questions by looking at the distribution.
Hi ...I have another question><
The number showing on the upper faces when two fair six-sided dice are tossed is observed. Consider events A and B defined as:
A - the total score is at least 8
B - at least one die achieves a score of 2 or less
Find 1. P(B') ( 3 dec pl)
2. P(A or B) ( 3 dec pl)
