#### Solution

Consider the statement pattern: [(p → q) ∧ q] → p

Thus the truth table of the given logical statement: [(p → q) ∧ q] → p

p | q | p → q | (p → q) ∧ q | [(p → q) ∧ q] → p |

T | T | T | T | T |

T | F | F | F | T |

F | T | T | T | F |

F | F | T | F | T |

From the above truth table we can say that given logical statement: [(p → q) ∧ q] → p is contingency.
