Vedclass · Answer

(C) Let the minimum percentage of the population of the town that should fall sick in order to raise the threat level be $x \%$. Given that the probability of a sick person being admitted to an $ICU$ is $10 \%$. Therefore, the probability of any person in the town being admitted to an $ICU$ is $10 \% 	ext{ of } x \%$. We are given that the threat level is raised if this probability exceeds $5 \%$. So, we set up the equation: $\frac{10}{100} 	imes x = 5$. Solving for $x$: $0.1x = 5 \Rightarrow x = \frac{5}{0.1} = 50$. Thus, at least $50 \%$ of the population must fall sick to raise the threat level. Hence, option $C$ is correct.
