WebAttempt: Rewrite as P ( x > 18.7) - P( x > 11.7) Using the phi function \begin{equation*} \phi(1.85) - \phi(-1.65) = (0.9678) - (0.0495) = 0.9183 \end Stack Exchange Network Stack … netflix scratchWebAverages of Euler-phi function and similar. What are the odds two numbers are relatively prime? This is known to be 6 π 2. The proof involves calculating averages of the Euler phi function. ϕ ( 1) + ϕ ( 2) + ⋯ + ϕ ( n) ≈ 3 ( n π) 2 + O ( n log n). So even though ϕ is rather noisy, its sum is relatively "quiet" behaving like a parabola. netflix scottish comedy series
