Question 5

Eva and Justin play a carnival game. They choose one special power and draw one character card; only the power can be chosen. Eva randomly draws Batman, Superman or Wonder Woman. Justin chooses fireball, tornado, lightning, telekinesis or invisibility. The table gives their final score; for example, Batman with fireball scores 59. They win a prize if their score is prime. Which power gives the highest chance of winning?

Interpretation: Assume the three character cards are equally likely.
