Question.3588 - Take a look at the the following problems: 1. A study of 500 Mercy University students revealed that 425 commute to school. Using these results, what is the probability of selecting a Mercy Student at random who does not commute to school? 2. What is the probability of guessing my birthday? (ignoring leap years) 3. What is the probability of selecting a Queen from a standard deck of cards? What is the probability of selecting the Queen of hearts? 4. Mike has made 71 of his last 100 free throws. What is the probability that he misses his next free throw? 5. The results of a blind taste test revealed that 80 out of 140 consumers preferred using self check when they had 5 items or less. Based on these results what is the probability of selecting a consumer at random who does not prefer using self check out when having 5 items or less? Try these problems on your own using the tools I provided earlier.
Answer Below:
students who do not commute = 500 - 425 = 75 Probability is 75/500 = 0.15 = 15% The probability of a correct birthday guess is 1/365 = 0.0274 = 27.4% probability of queen = 4/52 = 0.0769 =7.69% probability of queen of hearts = 1/52 = 0.0192 =1.92% probability of misses = 100 - 71 = 29. Therefore, probability of miss =0.29 =29% consumers who do not prefer self-checkout is 140 - 80 = 60. Therefore, the probability is 60/140 = 0.4286 = 42.86%.More Articles From Statistics
