Final answer:
The question is related to finding probabilities based on given information about California registered voters' opinions on a law and the Supreme Court's ruling.
Step-by-step explanation:
The question is related to probability as it involves finding probabilities based on given information. The probabilities to be calculated are:
a. P(C), which represents the probability of California registered voters who supported the law. This can be calculated by dividing the number of California registered voters who supported the law by the total number of registered voters.
b. P(B), which represents the probability of California registered voters who say the Supreme Court's ruling about the law is very or somewhat important to them. This can be calculated by dividing the number of California registered voters who support the law and say the ruling is important by the total number of registered voters who support the law.
