<h2>Answer:</h2><h2>The expected number of people who will attend this concert = 2260</h2>

Step-by-step explanation:

The concert organizers estimate people will attend if it is not raining = 19000

If its raining people will attend = 4000

On the day of the​ concert, meteorologists predict a 90​% chance of rain.

This means 10 % chance of not raining

The expected number of people = 90% (4000) + 10% (19000)

   = 360 + 1900

  = 2260

The expected number of people who will attend this concert = 2260
