As below:

Info; During the 2020 regular season, an NFL football kicker has converted 80% of all field goal kick attempts. A converted kick means that the kicker successfully kicked the football between the goal posts, so as to score three points. Assuming that this conversion rate continues to apply to the upcoming playoff games, use (and show) the appropriate formula used to compute the following probabilities. (Show ALL work and use your calculator to compute all the probabilities below. Assume the result for each field goal attempt is independent of each other)

Q: Probability ofconverting at least 50% of the nextsixfield goal attempts in the playoffs. Show all work

My thoughts are to use P(x) = _nC_x p^x q^n-x I wish to know if this is the correct formula to use for this? if not which calculation should I be using?
