The square root that you're looking to find can be written as:
√(0.85 * (1 - 0.85) / 1200)
First, calculate the value of 1 - 0.85:
1 - 0.85 = 0.15
Next, multiply 0.85 by 0.15:
0.85 * 0.15 = 0.1275
Now you have:
√(0.1275 / 1200)
Next, divide 0.1275 by 1200:
0.1275 / 1200 ≈ 0.00010625
Finally, take the square root of that quotient:
√0.00010625
Since this involves decimals, it's probably easiest to use a calculator. By doing that, we find:
√0.00010625 ≈ 0.010309
So the square root of 0.85 (1 - 0.85) divided by 1200 is approximately 0.010309.
