Two spreadsheet simulations compare results with expected probabilities. Coin heads occurred 48% of the time, and spinner red occurred 34% of the time on a 3-equal-section spinner. Which result is closer to its expected probability?
A
Neither result can be compared to an expected probability.
B
Coin heads, because 48% is 48 percentage points from 50%.
C
They are equally close to their expected probabilities.
D
Spinner red, because 34% is about 0.7 percentage point from 33.3%.
