1. (10 pts) Each of the possible six outcomes of a random experiment is equally likely. The sample space is {a, b, c, d, e, f). Let A denote the

event {a, b}, and let B denote the event {c, d, e}.Determine the following: \begin{array}{lllll} \mathrm{P}(\mathrm{A}) & \mathrm{P}(\mathrm{B}) & \mathrm{P}\left(\mathrm{A}^{\prime}\right) & \mathrm{P}(\mathrm{A} \cup \mathrm{B}) & \mathrm{P}(\mathrm{A} \cap \mathrm{B}) \end{array}
