Solution:
Given that there are white pencils and 6 red pencils in a box.
One pencil is selected at random and not replaced. Another pencil is randomly selected from the remaining pencils.
We are required to determine whether this event is independent or dependent.
Firstly, let us look at independent and dependent.
Two events A and B are said to be independent if the fact that one event has occurred does not affect the probability that the other event will occur. If whether or not one event occurs does affect the probability that the other event will occur, then the two events are said to be dependent.
