Generally these look like probability questions of multiple events.
If two events are independent from each other, you multiply them together - such as what is the probability of flipping a coin and getting heads, then rolling a die and getting a 2, would be 1/2 times 1/6.
If I have two events exclusive of each other - such as what is the probability of rolling a 1 or 2 on a die. I can't BOTH roll a 1 and 2 simultaneously - so the chance of rolling a 1 OR a 2 on one roll of a die is 1/6+ 1/6.
Keep in mind "die" is the singular form of "dice".
This should give a start.
