Suppose a recent government report indicates that 12% of the labor force is African American. Of the individuals in the labor fo
Anika [276]

Answer:

The probability that a randomly selected member of the labor force is African American given that he or she is unemployed is 0.2308.

Explanation:

The events are denoted as:

<em>A</em> = a member of a labor force is African American

<em>B</em> =  a member of a labor force is unemployed

The information provided is:

P(A)=0.12\\P(B|A)=0.11\\P(B|A^{c})=0.05

The Bayes' theorem states that the conditional probability of an event <em>E</em> given that another event <em>X</em> has already occurred is:

P(E|X)=\frac{P(X|E)P(E)}{P(X|E)P(E)+P(X|E^{c})P(E^{c})}

Use the Bayes' theorem to compute the value of P (A|B) as follows:

P(A|B)=\frac{P(B|A)P(A)}{P(B|A)P(A)+P(B|A^{c})P(A^{c})}=\frac{0.11\times 0.12}{(0.11\times 0.12)+(0.05\times (1-0.12))}=0.2308

Thus, the probability that a randomly selected member of the labor force is African American given that he or she is unemployed is 0.2308.

Economic growth are one of the things that can cause change in real Gdp.

melomori [17]

Answer:

Actual Cost of Supplier A:  $291.60

Actual Cost of Supplier B: $271.60

Explanation:

<u>Supplier A:</u>

Cost - 270

Shipping FOB shipping point

Purchase Discount = Invoice Price * Discount

For Supplier A, the invoice price is 270 and discount is 2/10 = 2%, so:

Purchase Discount = 270 * 0.02 = $5.4

Cost is:

270 + 27(shipping FOB point) - 5.4 = $291.60

<u>Supplier B:</u>

Cost - 280

Shipping Destination (so 0)

Purchase Discount = Invoice Price * Discount

For Supplier B, the invoice price is 280 and discount is 3%, so:

Purchase Discount = 280 * 0.03 = $8.4

Cost is:

280 - 8.4 = $271.60
