Answer:
Step-by-step explanation: The expected loss is 50 cents, we know that it is more likely to lose than win. It is therefore difficult to get-50, so the overall difference between the two possibilities is 2, 50/200=1/4, and the probability to win is 1/4, and the probability to lose is 3/4. Since (1/4)*3=3/4, the number of black balls is 3 times the number of white balls, so k=15.
Answer:
13
Step-by-step explanation:
32-2=30
30+7=37
50-37=13
The solution to this equation is x=4.6 because 19.32/4.2=4.6
-8 -8 = -16
You add -8 to -8
