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.

At a craft store, fabric comes in bolts that are a fixed number of inches wide.
kykrilka [37]
Hi, thank you for posting your question here at Brainly.

To solve this, you have to know the conversion factors. 

1 yard = 3 ft = 36 inches

Thus,

48 inches * (1 yard/36 inches) = 1.33 yards

This means that you need to buy at least 2 yards per bolt.
