I need help to understand thi question. - During the 2014 NFL regular season, kickers converted 88% of the field goals attempted. Assume that this percentage is true for all kickers in the upcoming NFL season. Find the probability that a randomly selected kicker who will try 4 field goal attempts in a game will - - miss all 4 field goal attempts Answer: P(0) = _nC_x p^x q^{n - x} = ₄C₄ (0.88)⁰ (0.12)⁴

= (1) (1) (0.00020736)

= 0.0002 if P is 0, why is _nC_x = ₄C₄ instead of ₄C₀ ??
