Details of ten international cricket games between two teams “Green” and “Blue”
are given in Table C. This table consists of matches played on different pitches,
across formats along with their winners. The attribute Pitch can take one of two
values: spin-friendly (represented as $S$) or pace-friendly (represented as $F$). The
attribute Format can take one of two values: one-day match (represented as $O$) or
test match (represented as $T$.
A cricket organization would like to use the information given in Table C to develop
a decision-tree model to predict outcomes of future games between these two teams.
To develop such a model, the computed InformationGain(C, Pitch) with respect to
the Target is ______ (rounded off to two decimal places).

Match Number	Pitch	Format	Winner (Target)
1	$S$	$T$	Green
2	$S$	$T$	Blue
3	$F$	$O$	Blue
4	$S$	$O$	Blue
5	$F$	$T$	Green
6	$F$	$O$	Blue
7	$S$	$O$	Green
8	$F$	$T$	Blue
9	$F$	$O$	Blue
10	$S$	$O$	Green

Given a dataset with $K$ binary-valued attributes (where $K>2$) for a two-class
classification task, the number of parameters to be estimated for learning a naïve
Bayes classifier is

Given the two-dimensional dataset consisting of 5 data points from two classes
(circles and squares) and assume that the Euclidean distance is used to measure the
distance between two points. The minimum odd value of $k$ in $k$-nearest neighbor
algorithm for which the diamond (⋄) shaped data point is assigned the label square
is ______.
