At the scene of a crime, the police have found a blood stain, a footprint, and some threads from a fabric. All are presumed to h
zubka84 [21]

Answer:

There is a 0.175% chance of finding such a person who has all three characteristics.

Out of 4,000 people, 7 people would likely to match all three characteristics.

Step-by-step explanation:

A crime has been committed and after analyzing the evidence, police has found out that:

  1. The criminal's blood type is a type found in only 10% of the population.
  2. The criminal's footprint is a size 13 men's shoe and only 7% of the population wears such shoe size.
  3. Only 25% of the population owns clothing made from a fabric that matches the thread samples found at the scene.

We required to find out the probability of selecting a random person who would match all of these characteristics.

Since it is given that the three characteristics are independent of each other then the required probability is  

P(all 3 characteristics) = P(1st characteristic)*P(2nd characteristic)*P(3rd characteristic)

P(all 3 characteristics) = (10/100)*(7/100)*(25/100)

P(all 3 characteristics) = 1750/1,000,000

P(all 3 characteristics) = 7/4000

P(all 3 characteristics) = 0.00175

P(all 3 characteristics) = 0.175%

So out of 4,000 people, 7 people would likely to match all three characteristics.

or

There is a 0.175% chance of finding such a person who has all three characteristics

When two people each measured a windows width, their results were 79 cm and 786 mm. Are these results equally precise? Explain.
rosijanka [135]

The second result is more precise because it's in millilitre,so if the first were to be fully precise,it should have been 78.6 cm.

Hope this helps!
