A vaccine has 90% probability of being effective in preventing a certain disease. the probability of getting the disease if the
IgorLugansk [536]
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.

Geometry help please!!
Tresset [83]
Using the Pythagorean Theorem we can solve this.

OB = radius = 32

OC = 13

Lets solve for CB, which is half the length of AB.

CB = SQRT(32^2 - 13^2)

CB = SQRT(1024 - 169)

CB = SQRT(855)

CB = 29.24

AB = 29.24 x 2 = 58.48 = 58.5.

The answer is 58.5
