What is the probability of choosing a blue gumball? c. What is the probability of choosing a green gumball? d. If you are going to reach into the bag and pull out a gumball at random, what color are you most likely to get? Explain. List all the outcomes when rolling a fair die. 8) LIST: _______________________________________________________________ a. What is the probability of getting a 5? b. What is the probability of getting a number less than 4? Roberto was playing a game that required spinning a spinner. On his first ten spins, he landed on four 9) different spaces. He landed on: one time Lose a Turn four times Move Forward One Space Move Forward Two Spaces three times Move Back One Space two times a. Based on this data, what is the probability that Roberto will spin on his next Move Forward Two Spaces spin? Why? b. Based on this data, what is the probability he will NOT land on on his next spin? Move Back One Space Why? Amy reached into a bag, recorded the color of the tile she picked, returned the tile and drew again. 10) These are the tiles she has drawn so far: red, red, blue, yellow, blue, red, green, red, blue, green Based on this data, a. What is the probability that her next draw will be red? b. What is the probability that her next draw will NOT be blue? c. If she draws 70 more times, how many times would you expect a green?
