Statistically 25181

Statistically, in a city of 100,000 inhabitants, 600 people die in one year. During the year, 2,000 people received hospital treatment, and 120 of them died there. Calculate the probability that a citizen who comes to the hospital for treatment will die there in the same year.

Correct answer:

p =  6.564 %

Step-by-step explanation:

$$\begin{gathered} p_1=\frac{600}{100000}=\frac{3}{500}=0.006 \\ {p}_2=\frac{120}{2000}=\frac{3}{50}=0.06 \\ p=100\cdot (p_1+p_2-p_1\cdot p_2)=100\cdot (\frac{600}{100000}+\frac{3}{50}-\frac{600}{100000}\cdot \frac{3}{50})=\frac{1641}{250}\%=6.564\% \end{gathered}$$
