Mutually Exclusive and Overlapping Events Practice

WRITE THE SETS AND SHOW WORK ON PAPER! You roll an 8 sided number cube. Event A: Roll a number less than 3. Event B: Roll a number greater than 5. Calculate P(A or B).

WRITE THE SETS AND SHOW WORK ON PAPER! You roll a 12 sided number cube. Event A: Roll an even number. Event B: Roll a multiple of 3. Calculate P(A or B).

A ∩ B =

• {1,3,5}

• {1,2,3,4,5,6,7,9}

• {8,10}

• {2,4,6,7,9}

A U B =

• {1,3,5}

• {1,2,3,4,5,6,7,9}

• {8,10}

• {2,4,6,7,9}

A^c =

• {1,3,5,7,8,9,10}

• {1,3,5,7,9}

• {7,8,9,10}

• {2,4,6}

B^c =

• {1,2,3,4,5,6}

• {1,3,5,7,9}

• {2,4,6}

• {2,4,6,8,10}

(A U B)^c =

• {1,2,3,4,5,6,7,9,10}

• {8,10}

• {1,3,5}

• {2,4,6,7,8,9,10}

(A ∩ B)^c =

• {1,2,3,4,5,6,7,9,10}

• {8,10}

• {1,3,5}

• {2,4,6,7,8,9,10}

P(B) = Type answer -> numerator/denominator Make sure you simplify!

P(A U B) =

Type answer -> numerator/denominator

No spaces!
