The summer location Wonderland experiences on average one sn

The summer location “Wonderland” experiences on average one snowfall per winter season.

(How large is the probability that, on a winter season, there are no snow- falls?

Sam has already answered P(x=0)=7.667648 ×10^-53)

(How large is the probability that, on a winter season, there are at least 3 snowfalls?

Sam has already answered P(x3)=2.26 × 10^-47 )

How large is the probability that, during two consecutive winter seasons, there are no snowfalls?

Solution

P(no snowfall in consecutive seasons) = P(no snowfall in first season) * P(no snowfall in second season) = 7.667648 ×10-53 * 7.667648 ×10-(53) = 5.8792825851904 × 10^(-105)
