Question 11
The spinner shown has five equal sectors labelled 1, 2, 3, 4 and 5. Spin it once. If it lands on a perfect square, flip a fair coin once. If it lands on a prime number, flip the coin twice. What is the probability of seeing at least one head? A fair coin has probability $1/2$ of heads on each flip.
Assume independent flips, independent of the spinner. Write the probability as $p/q$ in lowest terms with $q>0$, then enter $p+q$.
Enter one positive integer, without units.
