Question

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



A.
1

B.
2

C.
5

D.
9

Answer 1

So calculate the probability
that is
(desired outcomes)/(total possible outcomes)
desired oucomes=green
so take the spins from20 and 200 and 2000

tota=20
deriedoutcome=0
0/20=0

total=200
desired outcomes=7
7/200=0.035

total=2000
disired outcomes=95
95/2000=0.0475

average the 3 results

(0+0.035+0.0475)/3=0.027
0.027=x/20
multily both side by 20
0.5
round up
1

the answer is A, 1
