a plumber-accountant fixed your heater (probably very small, right? Not many people are both licensed plumbers and accountants), The key to remember here is that the question asks if the person who fixes the heater is most likely an accountant or an accountant and a plumber (AKA, a plumber-accountant). Strictly speaking, it's more likely s/he's an accountant than a plumber. BUT, the question asks what is more likely, which means it's a probability question. The Explanation: When you read this word problem, you intuitively jumped to the conclusion that the person was most likely a plumber because, well, plumbers fix water heaters. The Answer: The person is most likely an accountant. Is this person more likely:ĭid you answer a plumber? That's understandable, but you're wrong. That person comes to your house and uses a bunch of spare parts and then fixes it so you pay him or her for the repairs. You go to a person and ask them to check out your water heater. Suppose your water heater broke so you couldn't take a hot shower.
Or, maybe you're just a genius and you were right the first time in which case, good on you! 2. Or maybe you didn't spot the 30 in the 1030 of the third to last line. It seems totally obvious now that it's all done out slowly in front of you, but what made you slip up on that last addition the first time around is that when you were adding everything up quickly in your head, you never had to carry any ones until the very end, and when you finally do have to carry a one, you accidentally added it to the thousands spot rather than the hundreds because you were going so quickly. You were probs totally on a roll until you got to to the last addition.ģ080 + 1000 = 4080 (Yassss, almost done!)Įrrrr, what?! You def didn't get that before. The Explanation: This is just a simple case of your brain getting ahead of itself.
