Question 11

The spinner is divided into five equal parts. Spin once. If it lands on a perfect square number, flip a fair coin once. If it lands on a prime number, do not flip the coin. What is the probability that you flipped a coin and it landed heads up? If that probability is $p/q$ in simplest form, choose the value of $p+q$.
