For each of the following scenarios, decide if the outcome is random.
a) You enter a contest in which the winning ticket is selected from a large drum of entries. Was the winner of the contest random?
b) When playing a board game, the number of spaces you move is decided by rolling a six-sided die. Is the number of spaces you move random?
c) Before flipping a coin, your friend asks you to "call it." Is your choice (heads or tails) random?
