Issue: whether government should be given authorize to keep secret any information they wish.
输血: 最后一道PS题:说股票的几个在一个月每一天都是不同的,如果第二天的价格是$10, 每天的股价差的百分比不得超过50%,下面那个价格最不可能是这个月股票的价格? answer choice: $3\$6$9$19$29
靠后的一道题DS:给了一个饼图,分成三部分:红、黄、蓝,每部分有个标有颜色的球,还有个转动的箭头,(有点像大转盘的游戏)。问箭头转动后能指向红色球的概率。1)给了红色和黄色的概率 2)给了出了红色的概率 (备战:条件一记得不是很清楚了) |
