A carnival game had a spinning wheel with 20 equal-size sections: some red, some black, and some green. Every time the wheel was spun, the game attendant recorded the color selected. The table shows the results after 20, 200, and 2000 spins.
What is the best estimate of the number of green sections on the wheel?
Outcome Number of trials
20 200 2000
red 12 109 1028
black 8 84 879
green 0 7 95

\[\frac{95}{2000}=\frac{x}{20}\]

okay, i will tell u what i get in a sec...
OpenStudy (anonymous):
for solving x, i got 19
OpenStudy (misty1212):
solve that by
\[95\times 20=2000x\] or
\[x=\frac{95\times 20}{2000}\]
OpenStudy (misty1212):
you are off a bit. it should be
\[\frac{19}{20}\]
OpenStudy (misty1212):
which is pretty close to 1
