Answer:
9.87%
Step-by-step explanation:
We know that the clock must ring 4 times, but there must be 7 rings. The only way for this to happen is that of the 4 times, 3 that the bell rings 2 times and 1 that rings only once. So it would be:
2 + 2 + 2 + 1 = 7
So the final probability would be the multiplication of these events, therefore:
(2/3) * (2/3) * (2/3) * (1/3) = 0.0987
In other words, the probability is 9.87%
