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.
Cell phones The Pew Research Center asked a random sample of adult cell-phone owners from the United States their age and which type of cell phone they own: iPhone, Android, or other (including non-smartphones). The two-way table summarizes the data.

Suppose we select one of the survey respondents at random.
Mike鈥檚 pizza - You work at Mike鈥檚 pizza shop. You have the following information about the 9 pizzas in the oven: 3 of the 9 have thick crust and 2 of the 3 thick-crust pizzas have mushrooms. Of the remaining 6 pizzas, 4 have mushrooms.
a. Are the events 鈥渢hick-crust pizza鈥 and 鈥減izza with mushrooms鈥 mutually exclusive? Page Number: 356 Justify your answer.
b. Are the events 鈥渢hick-crust pizza鈥 and 鈥減izza with mushrooms鈥 independent? Justify your answer.
c. Suppose you randomly select 2 of the pizzas in the oven. Find the probability that both have mushrooms.
Roulette An American roulette wheel has 38 slots with numbers throughand , as shown in the figure. Of the numbered slots, are red, are black, and 鈥攖丑别 and 鈥攁re green. When the wheel is spun, a metal ball is dropped onto the middle of the wheel. If the wheel is balanced, the ball is equally likely to settle in any of the numbered slots. Imagine spinning a fair wheel once. Define events : ball lands in a black slot, and : ball lands in an even-numbered slot. (Treatand as even numbers.)

a. Make a two-way table that displays the sample space in terms of events and .
b. Find and.
c. Describe the event 鈥and 鈥 in words. Then find the probability of this event.
d. Explain why . Then use the general addition rule to compute .
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
