Answer and Explanation:
According to research on decision making, due to something called confirmation bias, Sandy might see the dime as evidence for the accuracy of astrology. Confirmation bias refers to our tendency to look for things and signs that will confirm what we already believe in. According to research in this area, we are biased in our beliefs and tend to ignore any information that may challenge them. Therefore, Sandy is likely to ignore everything that went wrong throughout her day and focus on her "luck" when finding the dime.
