Answer: c.) The probability of getting heads when flipping a coin
Step-by-step explanation:
a.) The probability of a florist selling roses on Valentine’s Day
This is a biased event because it has a too small range, ranging only to one day is not enough for a data set. This will be a overestimation which can't represent the whole.
b.) The probability of seeing a fireworks show on Independence Day
This is a biased event because it also has a small range, ranging only to one day is not enough for a data set. This will be a overestimation which can't represent the whole.
c.) The probability of getting heads when flipping a coin
This is not biased because there will be equal probability for getting heads or the opposite. The range is neutral as heads is half part of coin, and tails is the other part of coin.
d.) The probability of a college graduate earning more money than a high school graduate
This is a biased event, because it will be an obvious answer which having an obvious answer to one event will be biased.
