Answer:

A. 27

Step-by-step explanation:

There are 40 students and 90% of them take exams

      (40 students) * (0.9) = 36 students took exams

Of those 36 students, 75% (or 3/4) of them passed. Assuming passing exams means graduating:

      (36 students) * (0.75 ) = 27 students graduated

All athletes at the Olympic games are tested for performance-enhancing steroid drug use. The imperfect test gives positive resul
Nana76 [90]

Answer:

0.4%

Step-by-step explanation:

We have two independent events

  1. The athlete who is being tested for drugs actually is using steroids.
  2. The test went wrong indicating a false result.

The probability of 1) to happen is 0.04 because "4% of all registered athletes use steroids".

The probability of 2) ti happen is 0.1 because "The imperfect test gives positive results (indicating drug use) for 90% of all steroid-users"

Then the probability of 1) and 2) to happen is given by

P=P(1)*P(2)=(0.04)(0.1)=0.004=0.4%
