%N Fibonacci numbers whose decimal expansion does not contain the digit 1.

%C The probability that Fibonacci(n) contains no digit 1 decreases to 0 as n goes to infinity. Seems that its maximum value is Fibonacci(211) having 44 digits, none of them is 1.

%e 34 is a term since 34 is a Fibonacci number having no 1's. [corrected by _D. S. McNeil_, Nov 12 2010]

%t Select[Fibonacci[Range[0, 150]], DigitCount[#, 10, 1]==0&] (* _Harvey P. Dale_, Apr 18 2019 *)

%o (Magma) [Fibonacci(n): n in [0..150] | not 1 in Intseq(Fibonacci(n))]; // _Vincenzo Librandi_, May 09 2019

%Y Cf. A000045, A177194, A176253.
