How do i simplify to get 2 easy numbers. rounded to 4 decimal places

C⁴⁷₀(0.013)⁰(0.987)⁴⁷ +C⁴⁷₁(0.013)¹(0.987)⁴⁶+C⁴⁷₂(0.013)²(0.987)⁴⁵

^And

1-C⁴⁷₀(0.013)⁰(0.987)⁴⁷

Solution

C470(0.013)(0)(0.987)(47)=0

C471(0.013)1(0.987)(46)=C227.9964

C472(0.013)2(0.987)45=C545.0609

1-C470(0.013)0(0.987)47=1-0=1

THEN

C470(0.013)0(0.987)47 +C471(0.013)1(0.987)46+C472(0.013)2(0.987)45 = C773.0573

AND

1-C470(0.013)0(0.987)47=1
