Answer:
No. The method is not fair.
<span>The
probability of pulling a gold or a silver for the first time is 1/10. The
probability of getting the same color the second time is 1/9. The probability
of getting a different color on the second pullout is still 1/10. Therefore,
the chance that same colors will be
pulled out is higher than that of different colors. Betty has an advantage in the drawing by 1.1%.</span>
Solution:
Probability of same color:
1/10+1/9
9/90+10/90
21.1%
Probability of different colors
1/10+1/10
2/10
20%
<span>21.1%-20%=1.1%</span>
