PrepTest 106 - Section 1 - Question 3

Show summary

Support For any given ticket in a 1000-ticket lottery, it is reasonable to believe that that ticket will lose. ██████ ██ ██ ██████████ ██ ███████ ████ ██ ██████ ████ ████

Method of Reasoning

The author concludes that it’s likely no item in a set will have a property (being a winning ticket). His reasoning is that each individual item (lottery ticket) is unlikely to have that property.

Identify and Describe Flaw

This is the cookie-cutter flaw of confusing the properties of a part with properties of the whole. Just because each individual lottery ticket is unlikely to be a winner, it doesn’t mean that the lottery as a whole is unlikely to have a winner.
