672 is the correct answer
If 25% of the people <em>are</em> vaccinated, then 75% of the people are <em>not</em> vaccinated. Of those not vaccinated, each has a 50% chance of contracting the disease. The probability that someone is both not vaccinated and contracts the disease is (0.75)(0.5)=0.375.
The probability that someone is vaccinated and contracts the disease is (0.25)(0.1)=0.025 (it is multiplied by 0.1 because if the vaccine is 90% effective, then there is a 10% chance someone that is vaccinated can contract the disease.
Add these together for the total: 0.375+0.025=0.4
There is a 40% chance that someone chosen at random will contract the disease.
Hello!
I will make approximations below to the nearest whole number
A. 2√32≈11
B. 5+√18≈9
C. √24≈5
D. √52-3≈4
E. 3√14≈11
F. √20+√26≈10
Based off of what we see here our even numbers are 
and 
.
I hope this helps!
