MY ANSWER IS 5 THANK YOU FOR QUESTION
The original gross margin is (2.50 / 1.00) - 1 = (2.5 - 1) = 1.5 = 150%
the cost increases 0.25, is an increase of (0.25 / 1.00) = 25%
in order to keep the same gross margin, you need to increase the sale price by 25%
2.50*1.25 = 3.125
Then the gross margin is (3.125 / 1.25) - 1 = (2.5 - 1) = 1.5 = 150% ( same as original )
Answer:
The expected net gain to the player for one play is -$0.0526.
Step-by-step explanation:
To find the expected net gain, we multiply each outcome by its probability:
Player wins:
Earns $35.
1 out of 38 numbers, so probability 1/38.
Player loses:
Loses $1.
37 out of 38 numbers, so probability 37/38.
Expected value:
The expected net gain to the player for one play is -$0.0526.

so...
2/10 is a lot smaller than 3/5 (6/10)
