## Homework Statement

A source of liquid is known to contain bacteria, with the mean number of bacteria per cubic centimeter equal to 3. Ten 1 c.c. test tubes are filled with liquid. Calculate the probability that all 10 test tubes will show growth, that is contain at least 1 bacterium each. (use Poisson distribution)

## Homework Equations

P(r)=(e

^{-m}*m

^{r})/r!

## The Attempt at a Solution

Taking m=3;

N=10 (not used)

P(1)+P(2)+P(3)=0.5974

Answer provided is 0.600, is my solution correct?
