Step 1: Understand the problem.
Landuse classification using satellite imagery involves categorizing different land cover types (forest, water, urban, agriculture, etc.) based on spectral signatures. This is a problem of image classification, and several algorithms can be applied.
Step 2: Examine each option.
\begin{itemize}
\item Option (A): Maximum Likelihood
This is a supervised classification method widely used in remote sensing. It assumes the data follow a normal distribution and classifies pixels based on probability. Hence, this method is valid.
\item Option (B): Northwest Corner Method
This method belongs to Operations Research (used for solving transportation problems). It is unrelated to satellite image classification. Therefore, this option is invalid.
\item Option (C): K Means
K-Means clustering is an unsupervised classification method, commonly applied in remote sensing to partition pixels into clusters without prior training data. Hence, valid.
\item Option (D): ANN (Artificial Neural Networks)
ANNs are advanced machine learning models that can classify satellite images with high accuracy, especially with large datasets. Hence, valid.
\end{itemize}
Step 3: Final Selection.
Valid methods are: Maximum Likelihood, K Means, and ANN.
Final Answer: \[ \boxed{(A), (C), (D)} \]

P and Q play chess frequently against each other. Of these matches, P has won 80% of the matches, drawn 15% of the matches, and lost 5% of the matches.
If they play 3 more matches, what is the probability of P winning exactly 2 of these 3 matches?
