Final answer:
Given that team A has a 60% chance of winning, the probability of team B winning is calculated by subtracting team A's probability from 1, resulting in a 40% chance for team B's victory.
Step-by-step explanation:
If we are given that team A has a 60-40 chance of winning, then this implies that the probability of team A winning is 60%, or 0.60, since probabilities are often expressed as decimals. The remaining portion of probability must be assigned to team B, as these are mutually exclusive outcomes in a game setting (either team A wins or team B wins, but not both).
In this case, to find the probability of team B winning, we subtract the probability of team A winning from the total probability (which is always 1, or 100%). So, the calculation would be:
Probability of team B winning = 1 - Probability of team A winning = 1 - 0.60 = 0.40, or 40%
Hence, the probability of team B winning is 40%.
