标题[问题]这题我不太懂最後一句
时间Mon May 22 20:58:44 2006
Let the number of chocolate drops in a certain type of cookie have a
Poisson distribution .We want the probability that a cookie of this
type contains at least one chocolate drops to be greater than 0.99.
Find the smallest value that the mean of the distribution can take.
版上有位大大给我的推文是
P(X>=1)>0.99 1-e^-λ >0.99 求λ
ps 我看统计学的原文书很久 还是不知e^是什麽意思
请问有哪位好心人士知道吗 谢谢^^
