In a single experiment, a die is tossed and a spinner with the letters a, b, and c is spun. each letter is equally likely. find the sample space and then find the probability of getting a b. a.the sample space is 18. the probability of getting a b is 1/9b. the sample space is 18. the probability of getting a b is 1/3c. the sample space is 9. the probability of getting a b is 1/9d. the sample space is 9. the probability of getting a b is 1/18
