How do we get n = 5 by using bruteforce? Please explain this solution in detail. For clarification, screenshots are given below.
What detail exactly are you looking for that’s not in the solution?
I do not understand how we get n = 5 after the line 1 X (11/12) X (10/12)…< (1/2).
It’s bruteforce. For example, for n = 1, we have
1
which is not less than 0.5. For n = 2, we have
1 \times \frac{11}{12}
which is still not less than 0.5. Continue this process.
