Final answer:
The phrase 'to stand every chance of +ing' indicates a high likelihood of an event happening, meaning to have a good opportunity for doing something.
Step-by-step explanation:
The phrase 'to stand every chance of +ing' means to have a good opportunity for doing something. This implies that the likelihood of the event or outcome is high. In terms of probability, it is analogous to an event that is far more likely than not to happen. For example, if someone says you stand every chance of winning a contest because you are well-prepared, it suggests your probability of winning is much higher than losing. Unlike a coin toss where the outcome is 50 percent, here the percentage is tilted significantly in your favor.
