Given that P(BA) means the probability of event B occurring given that event A will occur or has occurred, which of the following correctly calculates this probability?

A) P(B)
B) P(A and B)/P(B)
C) P(A)/P(B)
D) P(A and B)/P(A)​

Answer :

Answer:

D

Step-by-step explanation:

the answer is d because b and a have to happen at the same time

To find the required probability the formula is, P(B|A) = P(A and B)/P(A)

The the correct answer is an option (D) P(A and B)/P(A)​

What is probability?

"It is finding out the possibilities of the occurrence of an event."

Formula to find the probability of an event:

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

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

n(S) is the total number of outcomes for an experiment"

What is conditional probability?

"It is the possibility of an event occurring, based on the occurrence of a previous event."

What is conditional probability formula?

the conditional probability of event A, given that event B has occurred

P(A|B) = P(A and B)/P(B)

For given example,

the probability of event B occurring given that event A will occur or has occurred,

Using conditional probability formula,

P(B|A) = P(A and B)/P(A)

Therefore, the correct answer is an option (D) P(A and B)/P(A)​
