A bag of candy contains chocolate hearts, vanilla hearts and gumballs. The number of pieces of heart shaped candy is 5 times the number if gumballs. If one piece of candy is to be chosen at random from the bag, the probability that a vanilla heart will be chosen is 4 times the probability that a chocolate heart will be chosen. If there are 16 vanilla hearts in the bag, what is the total number of piece of candy in the bag.?

这个题没法做,以为条件不完整.
原文“the probability that a vanilla heart will be chosen” 后面应该还有is……
这个概率需要给出来,这个题目才能做.
从英语语法的角度分析,这个句子也是不完整的,没有谓语…
看看是不是资料印刷出了问题……
再问：咳咳那啥..是我少抄了一句话不好意思- - 现在已经补起来了=v=谢谢提醒.~
再答：假设分别有x,y,z(为了简化，汉字略去部分) x+y=5z y/(x+y+z)=4*x/(x+y+z) 即 y=4x y=16 解出 x=4 y=16 z=4 total 24
