The great Zlatan Ibrahimovi always scores a goal if he manages to take no less than six shots in a game (and sometimes he scores even without shooting). The following is a probability distribution of the number of shots Zlatan Ibrahimovi must make to score a goal: a. Calculate the expected (mean) number of shots he takes to score a goal. (1) b. Calculate the standard deviation of this distribution. (2).
