- Dana Hills High School was considering going back to campus rather than remote instruction for the remainder of the semester. To make this decision, the school sent out a survey to students, parents, teachers, and staff to see if they would prefer remote or on campus instruction. The results of the survey are given in the table below. Find the probability that a person has no preference or is a student.

A new virus affects 3% of the Windows, 2% of the Apple, and 1% of the Linux operating systems. What is the probability a computer on this campus has the virus? If a randomly chosen computer on this compass has the virus, what is the probability it is a Windows machine?В. Forty five percent of the streets in an area have private guards for security. Three streets are selected at random: i. What is the probability all three of the selected streets have private guards? What is the probability none of the three selected streets has private guards? What is the probability at least one of the selected streets has private guards? iv. ii. iii. What is the probability at most two of the selected streets have private guards?
- WINDO In a survey of consumers aged 12 and older, respondents were asked how many cell phones were in use by the household. (No two respondents were from the same household.) Among the respondents, 208 answered "none," 285 said "one," 361 said "two," 140 said "three," and 56 responded with four or more. A survey respondent is selected at random. Find the probability that his/her household has four or more cell phones in use. Is it unlikely for a household to have four or more cell phones in use? Consider an event to be unlikely if its probability is less than or equal to 0.05. P(four or more cell phones) = (Round to three decimal places as needed.)
