问题 If the probability that Dave will go to class is 0.7, what is the probability that he will not go to class?
选项
答案 0.3
解析 The probability that Dave will go to class is 0.7, or 70%. Therefore, the probability that he will NOT go to class is 100% - 70%, or 30%, which is equivalent to 0.3, so either answer will be correct.
