There is a picture attached
francisco is playing a game with 3 green, 2 yellow, 4 red, and 3 black marbles in a bag. he has calculated the probability of drawing a yellow marble, not replacing it, and then drawing a red marble. explain the error in his solution.(the picture is fransisco's work)

Step-by-step explanation:

ample Response: The events are dependent, so the sample space changes for the second draw. After drawing the first marble, there are only 11 marbles left. The probability is (  

2

12

) (  

4

11

)  =  

8

132

, or  

2

33

.

a is the correct

answer:   x = 3 + √11     and     x = 3 - √11

step-by-step explanation:

x² - 6x + 9 = 11

(x - 3)² = 11

x - 3 = ±√11

    x = 3 ± √11

x = 3 + √11     and     x = 3 - √11
