Suppose your water heater broke so you couldn't take a hot shower. You go to a person and ask them to check out your water heater. 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. Is this person more likely:
Answers
Answer: The person is most likely an accountant
Explanation:
When you read this word problem, you artificially jump to the conclusion that the person was a plumber because plumbers fix the water heater. But, the question asks whether there's a lesser probability, which means it's a probability question.
rigorously speaking, it's more likely that he's an accountant than a plumber. The key to flash back then's that the question asks whether the person fixing the heater is likely to be an accountant or an accountant and a plumber( AKA, plumber- accountant).
So, the probability that
( a) have a plumber- accountant fix your heater( presumably too small, right? Not numerous people are both certified plumbers and accountants),
( B) an accountant fixed your heater( more an accountant being delved than a plumber- accountant) And also, in this situation, any plumber is of course also an accountant, so you really add those possibilities together.
A ≤ A B
or
Plumber- Accountants ≤ Plumber- Accountant Accountants
So, it was most probably an accountant!
