Question 458006: In a small town, the probability of a power outage during a rainstorm is 10%. find the following probabilities rounded to the nearest %. P(at least 2 outages in the next 5 rainstorms). P(at most 1 outage in the next 5 rainstorms)

You can put this solution on YOUR website! In a small town, the probability of a power outage during a rainstorm is 10%. find the following probabilities rounded to the nearest %.
----
Binomial Problem with n = 5 and p = 0.10
----
P(at least 2 outages in the next 5 rainstorms).
---
P(2 <= x <=5) = 1-P(0<= x<=1) = 1-binomcdf(5,0.1,1) = 0.0815
------------------
P(at most 1 outage in the next 5 rainstorms)
P(0 <= x <=1) = 0.9185
===========================
