Final answer:
The question deals with a hypothetical scenario involving the probability of a key player's participation in a game for the Los Angeles Lakers. Due to an apparent typo, we assume a 40% chance of the player being healthy, allowing us to explain how probability is represented in mathematics.
Step-by-step explanation:
The question refers to the probability of a key player's participation in an important game for the Los Angeles Lakers. However, there seems to be an error as the Lakers are not a baseball team; they are a basketball team. Assuming this is a hypothetical scenario for a math problem, if we consider that the question is about assessing the chance of the player being healthy enough to play, the potential probability value mentioned ("40?") is incomplete. Hence, we cannot calculate the exact probability without the full value. Probability in mathematics involves the chance of a particular event occurring, expressed as a percentage or a fraction. If we assume the complete value is $40%", then the probability that the key player will be able to participate in the game is 40 out of 100, or $0.4" in decimal form.
