To determine the probability of selecting a brown square, we need more context about the figure you mentioned, such as the total number of squares and the number of brown squares present. The probabilities you provided suggest that there may be a mix of fractions and whole numbers.
The probability \( P \) is calculated using the formula:
\[ P(\text{brown square}) = \frac{\text{Number of brown squares}}{\text{Total number of squares}} \]
If you can provide the specific numbers of brown squares and the total number of squares or any additional relevant information from the figure, I'd be glad to help you calculate or identify the correct probability from the options given (A, B, C, D).
