Erin just bought a bag of gumballs with eight different colors of gumballs. One of the colors is Erin’s favorite. The manufacturer claims that each color is equally likely in every bag. Erin opens the bag and pulls out one gumball. Since it is not her favorite color, she puts it back in the bag with the rest of the gumballs. She shakes the bag to remix the gumballs inside. Erin continues this process until she pulls out her favorite color. What is the expected number of gumballs that Erin will need to pull out of the bag until she gets her favorite color?
