Of all the people applying for a certain job 75% are qualified and 25% are not. The personnel manager claims that she approves q
Gwar [14]

Answer:

The probability is: 0.8889.

Step-by-step explanation:

Conditional Probability

We use the conditional probability formula to solve this question. It is

P(B|A) = \frac{P(A \cap B)}{P(A)}

In which

P(B|A) is the probability of event B happening, given that A happened.

P(A \cap B) is the probability of both A and B happening.

P(A) is the probability of A happening.

In this question:

Event A: Approved

Event B: Qualified

Probability of a person being approved:

80% of 75%(qualified)

30% of 25%(not qualified). So

P(A) = 0.8*0.75 + 0.3*0.25 = 0.675

Probability of a person being approved and being qualified:

80% of 75%, so:

P(A \cap B) = 0.8*0.75

Find the probability that a person is qualified if he or she was approved by the manager.

P(B|A) = \frac{P(A \cap B)}{P(A)} = \frac{0.8*0.75}{0.675} = 0.8889

The probability is: 0.8889.
