A spinner has three equally sized regions: blue, red, and green. Jonny spins the spinner times and gets blues in a row. If he spins the spinner more times, how many more blues is he most likely to get?
The correct option is :
b. more blues is he most likely to get.

Bull鈥檚-eye! In a certain archery competition, each player continues to shoot until he or she misses the center of the target twice. Quinn is one of the archers in this competition. Based on past experience, she has a probability of hitting the center of the target on each shot. We want to design a simulation to estimate the probability that Quinn stays in the competition for at least shots. Describe how you would use each of the following chance devices to perform one trial of the simulation.
a. Slips of paper
b. Random digits table
c. Random number generator
Color-blind men About of men in the United States have some form of red-green color blindness. Suppose we randomly select one U.S. adult male at a time until we find one who is red-green color-blind. Should we be surprised if it takes us or more men? Describe how you would carry out a simulation to estimate the probability that we would have to randomly select or more U.S. adult males to find one who is red-green color blind. Do not perform the simulation.
Double fault!A professional tennis player claims to get of her second serves in. In a recent match, the player missed of her first second serves. Is this a surprising result if the player鈥檚 claim is true? Assume that the player has a probability of missing each second serve. We want to carry out a simulation to estimate the probability that she would miss or more of her first second serves.
a. Describe how to use a random number generator to perform one trial of the simulation. The dot plot displays the number of second serves missed by the player out of the first second serves in simulated matches.
b. Explain what the dot at represents.
c. Use the results of the simulation to estimate the probability that the player would miss or more of her first second serves in a match.
d. Is there convincing evidence that the player misses more than of her second serves? Explain your answer.
Free-throw practice At the end of basketball practice, each player on the team must shoot free throws until he makes of them. Dwayne is a free-throw shooter. That is, his probability of making any free throw is . We want to design a simulation to estimate the probability that Dwayne make free throws in at most shots. Describe how you would use each of the following chance devices to perform one trial of the simulation.
a. Slips of paper
b. Random digits table
c. Random number generator
Mac or PC? A recent census at a major university revealed thatof its students mainly used Macs. The rest mainly used PCs. At the time of the census, of the school鈥檚 students were undergraduates. The rest were graduate students. In the census, of respondents were graduate students and used a Mac as their main computer. Suppose we select a student at random from among those who were part of the census. Define events G: is a graduate student and M: primarily uses a Mac.
a. Find P(G 鈭� M). Interpret this value in context.
b. Consider the event that the randomly selected student is an undergraduate student and
primarily uses a PC. Write this event in symbolic form and find its probability.
