*DIFFICULT QUESTION, PLEASE ANSWER* Which of the following is NOT a biased event? a.) The probability of a florist selling roses on Valentine’s Day b.) The probability of seeing a fireworks show on Independence Day c.) The probability of getting heads when flipping a coin d.) The probability of a college graduate earning more money than a high school graduate

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.

Hope this helps!! :)
