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?
