oh okay i see my mistake , thank you can you double check a few more

am i correct? is it true?

oh wait no its does pass, it would be true

i think its false, im not sure which is correct then ?

is it (-3,1) ?

This one is samilair to mine, im taking note of this as well

CPhill got this answer. I am confused which is correct.

Option A.....possible outcomes

(1, 1)  (2, 2)

(1, 2)  ( 2,5)

(2, 1)   (5,2)

(1, 5)   (5, 5)

(5, 1)

Expected vlalue  = (3/9)(8)  - (6/9)(2)  =   8/3 - 4/3  ≈ $1.33

Option B

Expected value (50/((1/8) - (1)(7/8)  ≈ $5.38

Ptiob B is better by  $ [ 5.38 - 1.33]  =  $4.05

how would i write this in money form ? Im confused. Could you explain?

oh okay now  I see where I made my mistakes Thank you for your explaination I will take notes on this. Could yu help me with the second question?
