94. 7 pounds of grapes costs 10.43 dollars. Now, solve for the costs of 3 pounds of grapes. There are different ways to solve this kind of situation. For my end, I will be showing the solution that I think is easier. => 7 pounds = 10.43 dollars. Find the unit rate first => 10.43 dollars / 7 = 1.49 dollars per pounds. Now, solve for the cost of 3 pounds => 1.49 * 3 = 4.47 dollars is the costs of 3 pounds of grapes.

Answer:

for independent A and B, P(A|B) = P(A)

Step-by-step explanation:

The definition of conditional probability is ...

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

When A and B are independent, ...

P(A&B) = P(A)·P(B)

so the conditional probability is ...

P(A|B) = (P(A)·P(B))/P(B) = P(A) . . . . . for independent A and B

In words, when A and B are independent, the probability of A given B is the same as the probability of A. That is, the probability of B has no effect on the probability of A.
