Answer:
P(2)=0.256
Step-by-step explanation:
We know that Nancy has noticed that 20 trucks pass by her apartment daily (24 hours). We conclude that for 1 hours, pass 20/24=5/6 trucks.
We calculate how many trucks pass for 3 hours:
3 · 5/6= 15/6=2.5=λ
We use a Poisson distribution:
P(k)=\frac{λ^k · e^{-λ}}{k!}
For 2 trucks we have that is k=2. We know that is λ=2.5
We caclulate the probability
P(2)=\frac{2.5² · e^{-2.5}}{2!}
P(2)=0.256
