4. A recent survey showed that a majority of Americans plan on doing their holiday shopping online because they don’t want to spend money on gas driving from store to store (SOASTA

shopping online and 3 prefer to do their holiday shopping in stores. A random sample of 3 of

these 10 shoppers is selected for a more in-depth study of how the economy has impacted their

shopping behavior.

a. what is the probability that exactly 2 prefer shopping online?
