Question 1075543: A manager of a restaurant knows that about 40% of
customers order at least one appetizer. What is the

That is 10 (number of ways 2 can be taken out of 5)*(.4)^2*(.6)^3. Notice that the probabilities add to 1 and the exponents add to 5
That product is 0.3456
For 3 out of 5, it would be 10*.6^3*.4^2
