Probability Calculation: Calculate the probability of the events happening with the given information. Please write BOTH the probability and the percentage chance.

1). You are playing a game with Dungeons and Dragons with some

friends. In order to defeat the goblins that are defending a magical

sword you have to either roll a 6 or higher on a 12 sided die OR roll

lower than 14 on a 20 sided die. What is the probability that you

defeat the goblins provided that you roll both dies? (Hint: Remember

that rolling the 12 sided die, and rolling the 20 sided die are

independent events).

2). You decide to go to Keenland with some friends. You reckon that

horse number 4 has a 7:1 chance of winning. What is the probability

that this horse wins?

If two events are independent how do we calculate the and probability, P(E and F), of the two events? (As a side note: this "and" probability, P(E and F), is called the joint probability of Events E and F. Likewise, the probability of an individual event, like P(E), is called the marginal probability of Event E.)
