"A blood bank for a local hospital has a supply of plasma for which some have been contaminated with a virus causing hepatitis.

If 7 of the 48 units in the supply are contaminated, what is the probability that a severely injured accident victim given 5 units of plasma will not be exposed to the hepatitis virus

Answer:

The probability that the victim not getting hepatitis virus is 0.4547  

Explanation:

We have given that 7 of 48 units of blood is contaminated with virus causing hepatitis.

So probability of getting hepatitis virus is =\frac{7}{48}=0.1458

So probability of not getting hepatitis virus = 1 - 0.1458 = 0.8542

It is given that severely injured accident victim given 5 units of plasma

So probability that the victim not getting hepatitis virus = 0.8542^5=0.4547

So the probability that the victim not getting hepatitis virus is 0.4547

A huge amount of water − 7 to 9 l − moves from the blood into the bowel every day, through osmosis and digestive secretions. sin
Alexus [3.1K]
The event order should be:

1. Ingesting food, the small bowel filled with food solutes and become hypertonic. It will attract water from the blood which is hypotonic
2. Food digested, some of it absorbed. The osmotic pressure inside bowel will be reduced.
3. All food is absorbed, the osmotic pressure reduced significantly makes it hypotonic. The blood attracts water as it is hypertonic. This will increase the blood volume
