A gambling game pays 4 to 1 and the chance of winning is 1 in 6. Suppose you bet $1 on this game 600 times independently.

3A Find the expected number of times you win.

3B Find the SE of the number of times you win.

3C Find the chance that you lose more than $50 (that is, your net gain in the 600 bets is less than -$50).

a) 0.342

b) 0.231
c) 0.625

honor code

a) 100

1/6*600=100

b) 9.1287

sqrt(n*p*(1-p))
sqrt(600*1/6*(5/6))=9.1287

a) 0.342

b) 0.231
c) 0.625

all are wrong!

a) 100
b) 9.1287

Correct! Thank you very much L13!

-50=4X-(600-X)

600-50=550=5X
X=110
So, 86.33394%

Sorry, 0.851

LOL. And you twerps really think a mooc certificate is going to get you a job or uni credit.

can't believe this. honor code!

Why do you care?
