Sarah flipped a pair of coins 60 times on 24 occasions, heads appeared on both coins. How is this outcome different from the expected outcome?

It occurred 9 more times than expected
it occurred 4 more times than expected
It occurred 6 fewer times than expected
It occurred the expected number of times

I'm confused on this question, and I need an explanation. Please
