What the problems look like

A few statements from this skill. Answers, hints and worked solutions live in the practice session.

  1. Warm-up

    The probability that event AA occurs is P(A)=311P(A) = \dfrac{3}{11}. Use the complement rule to find P(Ac)P(A^{c}), the probability that AA does not occur. Give your answer as a reduced fraction.

  2. Warm-up

    The probability that event AA occurs is P(A)=112P(A) = \dfrac{1}{12}. Use the complement rule to find P(Ac)P(A^{c}), the probability that AA does not occur. Give your answer as a reduced fraction.

  3. Warm-up

    The probability that event AA occurs is P(A)=411P(A) = \dfrac{4}{11}. Use the complement rule to find P(Ac)P(A^{c}), the probability that AA does not occur. Give your answer as a reduced fraction.
