1. Through random sampling it is known that a certain virus is spreading among the school population of a certain city. Within the city, 65% of students are in elementary school and 35% are in secondary school. It has been determined that approximately 24% of elementary students have symptoms of the virus and 12% of secondary students have symptoms of the virus. A. Assuming the data above is correct and the school district has 4,000 students, complete the following two-way table: Elementary Secondary Virus Symptoms No Symptoms 2,600 1,400 4,000 B. What is the probability that a randomly chosen student currently has NO Symptoms? C. Given that a randomly chosen student has NO Virus Symptoms, what is the probability that the student is in Elementary school? Include the probability equation for conditional probilities and show work:

Transcribed Image Text:1. Through random sampling it is known that a certain virus is spreading
among the school population of a certain city.
Within the city, 65% of students are in elementary school and 35% are in
secondary school. It has been determined that approximately 24% of
elementary students have symptoms of the virus and 12% of secondary
students have symptoms of the virus.
A. Assuming the data above is correct and the school district has 4,000
students, complete the following two-way table:
Elementary
Secondary
Virus Symptoms No Symptoms
2,600
1,400
4,000
B. What is the probability that a randomly chosen student currently has
NO Symptoms?
C. Given that a randomly chosen student has NO Virus Symptoms, what is the
probability that the student is in Elementary school?
Include the probability equation for conditional probilities and show work:
