Question

Fenway Park is the home of the Red Sox. Though generations have come and gone, Fenway Park remains, much like it did the day it opened on April 20, 1912. Today the Red Sox are playing the NY Yankees. If today is sunny 1000 people will attend the ballgame. If today is cloudy only 500 people will attend the ball game. If it rains only 100 people will attend the ball game. The local meteorologist states that the probability of a sunny day is4, a cloudy day is .5 and a rainy day is1. What is the number of people expected to attend today's game?

Explanation / Answer

The expected number of people who will attend the today's game is computed here as:

= 1000*P(sunny ) + 500*P( cloudy ) + 100*P( rainy )

= 1000*0.4 + 500*0.5 + 100*0.1

= 400 + 250 + 10

= 660

Therefore 660 is the number of people expected to attend today's game.
