Question
For Event A and Event B, P(A)=79 , P(B)=89 , and P(A and B)=5681 . Are the events independent or dependent?Responsesindependentindependentdependent
Solution
To determine if events A and B are independent or dependent, we need to check if the probability of A and B occurring together is the product of their individual probabilities.
The individual probabilities are given as:
P(A) = 7/9 P(B) = 8/9
The probability of both A and B occurring is given as:
P(A and B) = 56/81
If A and B are independent, then P(A and B) should be equal to P(A) * P(B).
Let's calculate P(A) * P(B):
P(A) * P(B) = (7/9) * (8/9) = 56/81
Since P(A and B) is equal to P(A) * P(B), we can conclude that the events A and B are independent.
