Q: What is the probability of rolling a 7 in Monopoly?

The probability is calculated as 6 favorable outcomes divided by 36 total outcomes, which equals 1/6 or approximately 0.167.

Q: Can the grid be used to calculate probabilities of other outcomes?

Yes, the grid can be used to calculate the probabilities of various outcomes by counting the number of favorable outcomes and dividing by the total number of possible outcomes.
