Suppose the number of a particular type of bacteria in samples of 1 milliliter (ml) of drinking water tend to be approximately normally distributed, with a mean of 85 and a standard deviation of 9. What is the probability that a given 1-ml will contain more than 100 bacteria
Answers: 2
![P(X100)=P(\dfrac{X-\mu}{\sigma}\dfrac{100-85}{9})\\\\=P(Z1.67)\ \ \ \ [Z=\dfrac{X-\mu}{\sigma}]\\\\=1-P(Zz)=1-P(Z](/tpl/images/0860/0730/643b6.png)
