Step-by-step explanation:

Step 1: Define

4x² - 16x + 5 = -2

Step 2: Solve for x

Isolate x terms:                    4x² - 16x = -7Factor GCF:                         4(x² - 4x) = -7Isolate x terms:                    x² - 4x = -7/4Complete the Square:        x² - 4x + 4 = -7/4 + 4Simplify:                               (x - 2)² = 9/4Square root both sides:      x - 2 = ±3/2Isolate x:                              x = 2 ± 3/2Evaluate:                              x = 1/2,  7/2

It is 2 out of 8 she will pick green and 3 out of 7 she will pick green but red and green would be 5 out of 5 so 50% chance

Ithink the answer is c
