標題[問題]這題我不太懂最後一句

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.
版上有位大大給我的推文是
P(X>=1)>0.99 1-e^-λ >0.99 求λ
ps 我看統計學的原文書很久 還是不知e^是什麼意思
請問有哪位好心人士知道嗎 謝謝^^
