Answer:
d. 15.3%
Step-by-step explanation:
There are a total of 4 + 10 + 7 + 5 = 26 marbles
P(pick a red) = 4/26 = 2/13 = .153 = 15.3%
I don't know the options, but I can say this:
if you bought it at 20 1/4 and you sell them at 25 1/4 then your win pro stock is the difference between those two numbers, which is 5. (25 1/4-20 1/4 =5)
and if you sell all of them, your profit will be 30*5=150 dollars.
