To calculate expected value,
We can add up the probability of all possible events.
The 2 possible events are either winning $50 or losing the prize, which is $ - 50
Expected value =
50 x 40 % + (-50) x 60%
= $-10
So the answer is $-10
Well if the window is 40 x 10 the L is 52 and the w 22
Exact form: 89/3
Decimal form:29.666666.....
Mixed number: 29 2/3
go to the link the person took and you’ll get the answer i believe.
