1)Y=165000(1-0.04)^t
2)y=165000(1-0.04)^20=?? Use the calculator
The expected value per game is -0.26. Over 1000 games, you can expect to lose $263.16.
To find the expected value, we multiply the probability of winning by the amount of winnings, the probability of losing by the amount of loss, and adding those together.
We have a 1/38 chance of winning; 1/38(175) = $4.61. We also have a 37/38 chance of losing; 37/38(5) = $4.87.
$4.61-$4.87 = -$0.26 (rounded)
To five decimal places, our answer is -0.26136; multiplied by 1000 games, this is $261.36 lost.
Part A = She incorrectly add 1 (4/4) with 3/4, so instead of getting 7/4 she got 8/4.
Part B=She needs 28/4 (7) cups for 4 batches because 4/1x7/4=28/4.
