A school wants to attract more students to its media center. The media specialist has been asked to conduct a survey to determin
e which new media items students would like the school to purchase for the media center. Which method should the media specialist use to conduct the survey? A) Survey the first 25 students in the media center during lunch.
B) Survey a random sample of all students based on student registration.
C) Survey any student who has checked out library materials in the last month.
Answer:So to get a 6 when rolling a six-sided die, probability = 1 ÷ 6 = 0.167, or 16.7 percent chance. So to get two 6s when rolling two dice, probability = 1/6 × 1/6 = 1/36 = 1 ÷ 36 = 0.0278, or 2.78 percent.
