(a) 8 balls
(b) 4 balls
Step-by-step explanation:
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>

Answer: 6456
Step-by-step explanation:
Ratio of yes to no= 7:5
Number if yes= 3766
Since total number of yes is 3766. To find the total number of votes, 3766 / (7/7+5)
= 3766/ (7/12)
= 3766 × 12/7
= 45192/7
= 6456
There were 6456 total votes
