coin 1 head tail
==================
coin 2 head tail
so 4 outcomes equally possible
head/head
head/ tail
tail/ head
tail/tail
head/head is 1/4 = p
60/4 = 15 times expected
24 - 15 = 9
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
