Question

johnny is challenged to a single-player game with an expected value of 1. which statement below is true?
○ it is a fair game.
○ it is a favorable game.
○ it is unfavorable game.
○ johnny cannot determine whether the game is fair without knowing the rules.

Explanation:

To determine the nature of the game, we use the concept of expected value. A fair game has an expected value of 0 (net gain/loss is zero). A favorable game has a positive expected value (player expects to gain), and an unfavorable game has a negative expected value. Here, the expected value is 1 (positive), so it's a favorable game. The option about not knowing rules is incorrect as expected value already tells us, and "fair" is wrong (expected value not 0).

Answer:

B. It is a favorable game.
