Robin tosses a fair coin and then draws a ball from a bag that contains one red, one blue, and one green ball. PART A: What are the possible outcomes for the experiment? PART B: Three balls-- one red, one blue, and one green-- are added to the bag. Will the total number of outcomes change as a result? Why or why not?

@HelpMePlease14

OpenStudy (helpmeplease14):

idk

pooja195 (pooja195):

ok well try dont say idk

OpenStudy (helpmeplease14):

no because the answer stays the same

pooja195 (pooja195):

yep, good job! The total number of outcomes will not change. This is because the chance of drawing a red ball is 2/6 the chances of drawing a blue ball is 2/6 and the chances of drawing a green ball is 2/6. So simplified there is a 1/3 chance that each color ball will be drawn. The amount of colors did not change and the chance of each ball being drawn did not change and therefore there is no increase in the possible outcome.
