At the "Ping Pong Ball Toss" fair booth at the fair you pay $2 to play. You have a 8% probability of winning. A) If 2000 people visited the booth how many of them would win. B) If the prizes given away cost $5. How much does the fair booth make off of those 2000 people?
This isn't a multiple choice question. It's a two part question: Part A) and part B)
2000 * 0.08
Wait so that's what I have to do in order to get the answer to A)?
2000 * 0.08 is the answer to A ( 8% = 0.08 as a decimal)
we would expect 8% of 2000 to win since that is what is stated in the problem yes.
ooooh. So the answer is 160? 160 people would win?
For part B you calculate the amount of money the fair booth takes in and th eamount its expected to give out in prize money. His profit is the difference.
160 yes
2000 pay in $2, the table pays out 160 at $5 whats the tables expected profits for 2000 players?
$3,200 ?
4000 - 5*160
yes
YAY!
Thanks peeps
