Download Q&AQ. A certain disease affects 1 in every 200 people. If a random sample of 1000 people is taken, how many are expected to be affected? (2019)
Q. A certain disease has a 10% chance of being transmitted from an infected person to a healthy person. If there are 50 infected individuals, what is the expected number of transmissions if each interacts with one healthy person? (2023)
Q. A certain disease has a basic reproduction number (R0) of 3. If one infected person enters a population of 1000, how many people could potentially be infected after one generation? (2021)
Q. A certain disease has a mortality rate of 10%. If 500 people are infected, how many are expected to survive? (2019)
Q. A vaccine is 80% effective in preventing a disease. If 1000 people are vaccinated, how many are expected to still contract the disease? (2019)
Q. If a certain disease affects 1 in every 1000 people, what is the expected number of cases in a population of 50,000? (2020)
Q. If a disease has a 15% prevalence in a population and a test has a 95% specificity, what is the probability of a false positive result? (2021)
Q. If a disease has a basic reproduction number (R0) of 2.5, how many people can one infected person potentially infect in 3 generations? (2023)
Q. If a disease has an incidence rate of 0.1% in a population of 1,000,000, how many new cases are expected in a year? (2022)
Q. If a disease spreads at a rate of 3% per week, what will be the total percentage of the population infected after 4 weeks, assuming no recovery? (2021)
Q. If a person has a 20% chance of contracting a disease and a 30% chance of recovery, what is the probability that the person will contract the disease and not recover? (2022)
Q. If a test for a disease has a sensitivity of 90% and a specificity of 95%, what is the probability that a person who tests positive actually has the disease, given that the prevalence is 1%? (2022)
Q. If a vaccine reduces the risk of infection by 75%, what is the probability of infection after vaccination if the initial probability of infection is 0.2? (2020)
Q. If the average incubation period of a disease is 14 days, how many days will it take for 3 incubation periods to pass? (2020)
Q. If the mortality rate of a disease is 5% and 2000 people are diagnosed, how many deaths are expected? (2023)
Q. In a clinical trial, 60% of patients showed improvement after treatment. If 150 patients were treated, how many patients are expected to show improvement? (2022)
Q. In a population of 1000, if 50 people are infected with a disease, what is the prevalence rate of the disease? (2023)
Q. In a study, it was found that 70% of patients with a certain disease are male. If there are 400 patients, how many are expected to be male? (2020)
Q. What is the probability of a person being diagnosed with a disease if the prevalence of the disease in a population is 2% and the test for the disease has a sensitivity of 90% and a specificity of 95%? (2021)
