Tom and Mary wanted to play Candy Crush on their father's phone. However, neither of them knew the password to unlock the phone. First, Tom started to press numbers on the keypad randomly. After three unsuccessful attempts, Mary stopped him. Then, Mary tried to guess what numbers their father would use. Based on her previous experience, she wrote down three sets of numbers and started to try these. Her second set of numbers worked to unlock the phone. Both Tom and Mary were very excited and started to play Candy Crush on the phone.
In the story above, what problem-solving approaches/strategies did Tom and Mary use? For each approach/strategy, please identify it clearly, provide an explanation for it, and discuss one strength and one weakness of this approach.
