A spinner with three equal spaces (labeled A,B, and C) is spun. If the spinner lands on A or C a coin is flipped. If the spinner lands on B a standard 6-sided dice is rolled. What is the probability of spinning a B and rolling a prime?

  • Math -

    Prob(B) = 1/3
    prob(prime) = 3/6 = 1/2

    Prob(B, then a prime) = (1/3)(1/2) = 1/6
