A certain firm has plants A, B, and C producing respectively 35%, 15%, and 50% of the total output. The probabilities of a non-d

Sliva [168]

Answer:

There is a 44.12% probability that the defective product came from C.

Step-by-step explanation:

This can be formulated as the following problem:

What is the probability of B happening, knowing that A has happened.

It can be calculated by the following formula

$P = \frac{P(B).P(A/B)}{P(A)}$

Where P(B) is the probability of B happening, P(A/B) is the probability of A happening knowing that B happened and P(A) is the probability of A happening.

-In your problem, we have:

P(A) is the probability of the customer receiving a defective product. For this probability, we have:

$P(A) = P_{1} + P_{2} + P_{3}$

In which $P_{1}$ is the probability that the defective product was chosen from plant A(we have to consider the probability of plant A being chosen). So:

$P_{1} = 0.35*0.25 = 0.0875$

$P_{2}$ is the probability that the defective product was chosen from plant B(we have to consider the probability of plant B being chosen). So:

$P_{2} = 0.15*0.05 = 0.0075$

$P_{3}$ is the probability that the defective product was chosen from plant B(we have to consider the probability of plant B being chosen). So:

$P_{3} = 0.50*0.15 = 0.075$

$P(A) = 0.0875 + 0.0075 + 0.075 = 0.17$

P(B) is the probability the product chosen being C, that is 50% = 0.5.

P(A/B) is the probability of the product being defective, knowing that the plant chosen was C. So P(A/B) = 0.15.

So, the probability that the defective piece came from C is:

$P = \frac{0.5*0.15}{0.17} = 0.4412$

There is a 44.12% probability that the defective product came from C.

We use mathematical induction to prove things when:

scoray [572]

Answer:

We have two cases.

Step-by-step explanation:

A proof by Induction consists of two cases, the base case (or basis) and the induction step. Induction is a style of argument we use to convince ourselves and others that a mathematical statement is always true. Many mathematical statements can be proven by simply explaining what they mean.

The heights of South African men are Normally distributed with a mean of 69 inches and a standard deviation of 4 inches. What is

vekshin1

Answer:

the probability that a randomly selected South African man is taller than 72 inches is 0.2266

Step-by-step explanation:

The heights of South African men are Normally distributed with a mean of 69 inches and a standard deviation of 4 inches

population mean(m) = 69 inches

population standard deviation(s) = 4 inches

Therefore, the number of standard deviation above mean (z score) = (x - m)/s

In this case, x = 72 inches

z score = (72 - 69)/4 = 3/4 = 0.75

Probability that a randomly selected South African man is taller than 72 inches P(x>72) = 1 - P(x<72) = 1 - z(0.75) using the z table,

P(x>72) = 1 - 0.77337 = 0.2266

therefore, the probability that a randomly selected South African man is taller than 72 inches is 0.2266
