Question

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

(1 point)
It occurred 6 fewer times than expected.
It occurred 4 more times than expected.
It occurred 9 more times than expected.
It occurred 4 fewer times than expected.

Answer 1

since for each toss the probability is 0.5 for getting a head, we expect there to be 60*.5= 30 heads in 60 tosses, so there are 6 fewer than expected

Answer 2
