A researcher randomly surveyed 1,477 farmers to determine the geographical region in which they farm and the types of crops that grow there. The two-way table displays the data.

Suppose a farmer from this survey is chosen at random. Let M = farmer lives in the Midwest and V = farmer grows vegetables. What is the value of P(V|M)?

A) 251/72
B) 168/437
C) 723/1477
D) 251/365

Answer:

the answer is 251/723

Step-by-step explanation:

just took the test and also its asking for the (midwest farmer vegetables) so youd look at midwest and find the vegetable row and it would be 251 then since its asking for only vegetables you'd go across the row and locate the total vegetables which is 723. THE A OPTION IS MISTYPED ITS 251/723.

The value of P(V|M) is 251/365.

The correct answer is option (D)

What is probability?

"Probability is a branch of mathematics which deals with finding out the likelihood of the occurrence of an event."

Formula of the probability of an event A is:

P(A) = n(A)/n(S)

where,  n(A) is the number of favorable outcomes,

n(S) is the total number of events in the sample space.

What is conditional probability?

"It is the probability of an event occurring given that another event has already occurred."

Formula for conditional probability:

The probability of event A occurring given that event B has already occurred is,

P(A|B) = P(A ∩ B)/P(B)

where, P(A ∩ B) the joint probability of events A and B

For given example,

n(S) = 1477

Event M = farmer lives in the Midwest

⇒ n(M) = 365

So, the probability of farmer lives in the Midwest would be,

⇒ P(M) = n(M)/n(S)

⇒ P(M) = 365/1477

And event V = farmer grows vegetables.

⇒ n(V) = 723

The probability of farmer grows vegetable would be,

⇒ P(V) = n(V)/n(S)

⇒ P(V) = 723/1477

The number of farmers who grows vegetables and lives in the Midwest are,

n(A ∩ B) = 251

So, the probability that the farmers grow vegetables and live in the Midwest would,

⇒ P(M ∩ V) = n(A ∩ B)/n(S)

⇒ P(M ∩ V) = 251 / 1477

Now, we need to find P(V|M).

Using the formula of conditional probability,

⇒ P(V|M) = P(M ∩ V) / P(M)

⇒ P(V|M) = (251/1477) / (365/1477)

P(V|M) = 251/365

The correct answer is option (D)
