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
Answer:
Third choice, 3/4
Step-by-step explanation:
Add all the cubes together, 12 + 5 + 3 = 20
There's a 12/20, which is 3/5, chance you'll get a green cube
5/20, which is 1/4, chance you'll get a blue cube
And there's a 3/20 chance you'll get a yellow cube
The probability of not getting a blue cube is 12/20 + 3/20 = 15/20 = 3/4
