Will give ! 3 1. a spinner has six sections of equal shape and size. each section is either black or white. the table shows the result of an experiment when the spinner was spun 76 times: result of spin black white number of spins 19 57 based on the data, which of the following best describes the experimental probability of the arrow landing on a black or white section of the spinner? (5 points) select one: a. the spinner is 3 times more likely to land on white. b. the spinner is 3 times more likely to land on black. c. the information cannot be concluded from the data. d. the spinner is equally likely to land on black or white. 2. two groups performed an experiment separately by tossing a coin in the air. group p performed 50 trials and group q performed 100 trials. each group recorded the results in the table below: group heads tails p 35. 15 q 53 47 what conclusion can be drawn about the number of trials and the probability of the coin landing on heads or tails? select one: a. the experimental probability and the theoretical probability for group p is the same. b. the experimental probability and the theoretical probability for group q is the same. c. the experimental probability is closer to the theoretical probability for group q than group p. d. the experimental probability is closer to the theoretical probability for group p than group q. 3. the teacher of a seventh-grade class flipped a coin 100 times. the students recorded the results in the table shown below: side of coin landed on heads tails number of flips 56 44 which of the following best describes the experimental probability of getting tails? select one: a. the experimental probability is same as the theoretical probability. b. the experimental probability is 6% lower than the theoretical probability. c. the experimental probability is 6% higher than the theoretical probability. d. the experimental probability cannot be concluded from the data in the table.

Monitors manufactured by tsi electronics have life spans that have a normal distribution with a standard deviation of 1800 hours and a mean life span of 20,000 hours. if a monitor is selected at random, find the probability that the life span of the monitor will be more than 17,659 hours. round your answer to four decimal places.
