Based on Entropy ,which attribute (temp or windy) should be put to the root node ( first level) of the decision tree?

Class/label	Temp	Windy
Don't play	95	false
Don't play	90	true
play	77	false
play	70	true
play	68	false
Don't play	60	true
play	55	false
play	50	false

Entropy = -p - P_{i *}log2 P_i

_{a) Compute the overall entropy of the whole datset without splitting ?}

_{b) Compute the result entropy if we split on windy ?}

_{C) Compute the minimum entropy if we split on tem}

_{D) compare the results from c)and d) , decide which attribute is best to put to root node .}
