However, this result is not entirely accurate, as it doesn't account for the actual calculation of 0.9^18 . A more precise approach is to calculate the probability of failing all 18 attempts and then subtract that from 1:
This means it takes roughly intervals to cut the value in half (50%). 0.9^18
0.3874×0.3874≈0.15010.3874 cross 0.3874 is approximately equal to 0.1501 However, this result is not entirely accurate, as
The concept of 0.9^18 has practical applications in: this result is not entirely accurate
