I have This probability problem and I don't know how to do it:

**A company makes plastic panel used in automobiles. The panel production process is such thast the number of flaws on a panel follows a Poisson process with a mean of 0.03 flaws per panel.**

*1- If one panel is randomly selected from the production process, what is the probability it has no flaws.*

**My solution:**

lambda=0.03*1=0.03

f(0,0.03)=(e^(-0.03)*(0.03)^0)/(0!)

lambda=0.03*1=0.03

f(0,0.03)=(e^(-0.03)*(0.03)^0)/(0!)

*2- if 50 panesl is randomly sampled from the production process, what is the probability it has no flaws.*

**No solution here. I am not sure but it is the same as above but with lambda=0.03*50??**

*3- What is the expected number of panels that need to be sampled before flaws are found?*

No solution indeed!

Please can I have some help with this problem?
