When a survey of 800 people was done, 55% of those surveyed said they ate candy, 65% said they ate chips and 90% said they ate hot dogs. What is the smallest possible number of people who said they ate candy, chips and soda?
The probability of all events occurring is found by multiplying the probabilities of the individual events.
.55 * .65 * .90 = ?
