    An OR gate is the boolean function defined of:

    A) \[f({{x}_{1}},{{x}_{2}})={{x}_{1}}{{x}_{2}};{{x}_{1}},{{x}_{2}}\in \{0,1\}\]

    B)                   \[f({{x}_{1}},{{x}_{2}})={{x}_{1}}+{{x}_{2}};{{x}_{1}},{{x}_{2}}\in \{0,1\}\]

    C)                   \[f({{x}_{1}},{{x}_{2}})={{x}_{1}};{{x}_{1}},{{x}_{2}}\in \{0,1\}\]

    D)                   \[f({{x}_{1}},{{x}_{2}})={{x}_{2}};{{x}_{1}},{{x}_{2}}\in \{0,1\}\]

    Correct Answer: B

    Solution :

    In an OR gate the boolean function \[f({{x}_{1}},{{x}_{2}})\]is defined as \[f({{x}_{1}},{{x}_{2}})={{x}_{1}}+{{x}_{2}},{{x}_{1}},{{x}_{2}}\in \{0,1\}\]
