Question
A national standard requires that public bridges over
ranges from 0 (poorest rating) to 9 (highest rating). A group of engineers used a probabilistic model to forecast the inspection ratings of all major bridges in a city. For the year 2020, the engineers forecast that
20
feet in length must be inspected and rated every 2 years. The rating scale 6%
of all major bridges in that city will have ratings of 4 or below. Complete parts a and
b.
a. Use the forecast to find the probability that in a random sample of
10
major bridges in the city, at least 3 will have an inspection rating of 4 or below in 2020.P(x≥3)=
