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 (

the graph in the attached figure

step-by-step explanation:

we have

using a graphing tool

the graph in the attached figure

the roots are ( x-intercepts) x=-0.5,x=1,x=3

the y-intercept is the point (0,3)

answer: 80,000

step-by-step explanation:

the population doubles every day.

10,000*2=20,000 day 4

20,000*2=40,000 day 5

40,000*2=80,000 day 6
