ASAP! WILL BRAINLIEST PERSON WHO ANSWERS FIRST! PLEASE!
What role does the Automated Surface Observing Systems (ASOS) play in weather forecasting?
It is a fleet of weather balloons.
It is a system of radar sensors used to track storms.
It is the nation's primary weather-observing network.
It provides weather reports much like the National Weather Service.

It is the nations primary weather observing network

Step-by-step explanation:

The ASOS are automated sensor suites created in a join effort by NWS FAA and DOD and are relied on to track meteorological advancements. They are considered the nations primary weather observing network. I'm sorry for the delayed response as I attempted to answer this already, but my answer was deleted with the explanation of "I'm sorry this content is not allowed" with two fidget spinner emojis.

The experiment could be considered as a Bernoulli trial, modeled by the Binomial distribution.

n = 20, number of trials
p = 1/2, the probability of success
q = 1-p = 1/2, probability of failure

The probability of at least 14 successes in 20 trial is
P(success>=14) = ₂₀C₁₄ p¹⁴ q²⁰⁻¹⁴
  

= 0.037

0.037
This answer is plausible.
