Let
Number of balls
For a box, the probability that there are N balls in it is:
For 2 boxes, it is:
From the question, we have:
Favorable outcome
To solve for N, we have:
Divide both sides by 2
Take log of both sides
Apply law of logarithm
Make N the subject
Approximate
Solving (b): Balls in one of the two boxes.
Here, we assume that each ball will have almost the same number of balls at a given instance;
Hence, we have:
<em>4 balls in each box</em>
