- Two 6 sided dice are thrown and the scores of each dice are added together. Create a probability space of the possible outcomes. Below P(X) means the probability the sum of the scores is X. Use your probability space to find which of the following are correct. Note more than one answer may be correct. You should check each one and select all answers you believe are correct. P(X=8) = 36 A. 7. P(X2 10): 36 4 C P(X=6) =- 36 15 P(X<7) = 36 %3DGroups of adults are randomly selected and arranged in groups of three. The random variable x is the number in the group who say that they would feel comfortable in a self-driving vehicle. Determine whether a probability distribution is given.
