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)

Thanks
