1. Given a transaction database for mining association rule as follows:

TID Items

100 A C D

200 B C E

300 A B C E

400 B E

Forgiven support count = 2, which one of the followingstatement is incorrect?

• The rule B,C->E and the rule C->B,E-have the same confidence value.
• The rule B,C -> E and the rule B,E->C have the same support value.
• The rule B,C->E and the rule C,E->B have the sameconfidence value.
• The rule B,C->E and the rule C,E->B have the samesupport value.

1. Given a database table containing weather data as follows:

Outlook Temperature Humity Windy Class: Play

Sunny Hot High False No

Sunny Hot High True No

Overcast Hot High False Yes

Rainy Mild High False Yes

Rainy Cool Normal False Yes

Rainy Cool Normal True No

Overcast Cool Normal True Yes

Sunny Mild High False No

Sunny Cool Normal False Yes

Rainy Mild Normal False Yes

Sunny Mild Normal True Yes

Overcast Mild High True Yes

Overcast Hot Normal False Yes

Rainy Mild High True No

WhereOutlook, Temperature, Humidity, and Windy are the input variables (predictors), andPlayis the output variable (response or outcome).For the given sample,

X =(Outlook = 'Sunny',Temperature = 'Mild' , Humidity = 'High' ,Windy = 'False')

Please compute the conditional probabilityP(X|PLAY='Yes').
