Project #13008 - Biostatistics

A blood-borne fungal infection is known to kill 50% of those affected within 1 year.  There are three people affected.

 

 

 

 

            What is the probability that all three will die within the year?

 

 

 

 

 

 

 

            What is the probability that at least one will die within the year?

 

 

 

 

A blood bank has available 10 units of A+ blood.  In fact, four are contaminated with serum hepatitis.   

 

Three units are randomly selected for use with three patients. How many different ways can we select three units of blood from the 10 available unit?

 

 
 

 

 

 

 

 

 

 

 

 

 

 

 

Now we are going to give these blood units to three different patients.  What is the probability that exactly one of these patients will be exposed to hepatitis from this source?

 

 

 

 

 

 

 

 

What is the probability that at least two of the three will be exposed to hepatitis?

 


Among diabetics, the fasting blood glucose level (X) may be assumed to be approximately normally distributed with a mean of 106 mg/100ml and standard deviation of 8mg/100ml.

 

Find P(X < 120)

 

 
 

 

 

 

 

 

 

 

 

 

 

 

Find P(X < 100)

 

 
 

 

 

 

 

 

 

 

 

 

 

 

 

Find P(106 < X < 110)
