Dragon Dice is a tabletop game that uses modified dice to roll for the values 1, 2, 3 and 4 (note that the die is not fair). Let the random variable D represent the value of a single roll of the die.
The table below represents the probability distribution for the random variable D. Determine the missing value so that the probability distribution is valid.
| x | P(D=x) |
| 1 | |
| 2 | 0.26 |
| 3 | 0.34 |
| 4 | 0.28 |
True or False: The random variable D is a continuous random variable.
Compute the probability that at most a 2 is rolled on a single roll of the die.
On your turn, you attempt to capture a Giggling Goblin with a stomp attack using two dice. To capture the Giggling Goblin, you must roll a total of at least 5. On the first die roll you roll a 1. Choose the most correct statement concerning your chances of capturing a Giggling Goblin on this turn.
Group of answer choices
a. There is no way to capture a Giggling Goblin since P(D≥5)=0.
b. There is a 28% chance to capture a Giggling Goblin since P(D=4)=0.28.
c. There is no way to capture a Giggling Goblin since P(D=5)=0.
d. There is a 72% chance to capture a Giggling Goblin since P(D=4)=0.28 and P(D<4)=1−P(D=4)=1−0.28.
