- Suppose that you flip a coin 11 times. What is the probability that you achieve at least 4 tails?5. A tire company produced a batch of 6300 tires that includes exactly 250 that are defective. If 4 tires are randomly selected for installation, what is the probability that they are all good? (Do the calculations “without replacement”)Suppose that you flip a coin 13 times. What is the probability that you achieve at least 6 tails?
- Suppose that you flip a coin 13 times. What is the probability that you achieve at least 7 tails?5. A bag contains 20 purple marbles, 15 red marbles, and 5 blue marbles. What is the probability of randomly selecting a purple marble, not putting it back, and then randomly selecting a blue marble? (Express your answer as a decimal rounded to two places.)16. In an experiment, a two-sided coin is tossed three times. After each toss, the result (heads or tails) is recorded. What is the probability that LESS THAN two tails occur in the three tosses?
- What is the expected number of times you would have to spin a roulette wheel to win 3 times in a row betting on a number?Suppose that you flip a coin 13 times.
