The probability for event A is 0.3, the probability for event B is 0.5, and the probability of events A and B is 0.25. Are the e vents independent?
2 answers:
Answer:
no, because p(a) times p(b) is not equal to p(a and b)
Step-by-step explanation:
so its no, and then the second option for the second box. just did the assignment so i know its right! :)
For this case we have to:
Two or more events are independent when the occurrence or non-occurrence of one event has no effect on the probability of occurrence of the other event.
By definition, A is independent of B if and only if:
(P∩B) = P (A) P (B)
We have to:
So:
According to the statement
So, the events are not independent!
ANswer:
They are not independent!
