Q:
Defects in a certain wire occur at the rate of one per 10 meter.
Assume the defects have a Poisson distribution.
What is the probability that :
- a 20-meter wire has no defects?
- a 20-meter wire has at most 2 defects?

Q:
For two events V and W which are not mutually exclusive, you are given the
following information:
- \( \mathrm{P}(\mathrm{V})=0,35 \)
- \( \mathrm{P}(\mathrm{W})=0,55 \)
- \( \mathrm{P}(\mathrm{V} \) or W\( )=0,8 \)
Let the value of \( \mathrm{P}(\mathrm{V} \) and W\( )=x \).
