There is only one change of sign, so there is only one possible positive root.
There are five changes of signs, so there are 5,3 or 1 possible negative roots.
The number of complex roots can be equal to 4,2 or 0 (degree of a polynomial - possible positive roots - possible negative roots)
| Red |Green | Brown Total
<span>Smile |0.100 | .300 | .10 0.50</span>
<span>No smile |0.200 | .150 | .15 0.50
Total 0.30 0.45 0.25 1.00
The probability of choosing red candy is 0.10
The probability of choosing no smile candy is 0.50
