Problem 1 (2 Points)
You are at a mountain resort and wish to dine at three different restaurants. A total of 8 restaurants are available, but only two of the eight serve sea food. However, you as a diner do not know that only two restaurants serve sea food. Find the number of ways in which you can select a restaurant for dining so that at least one of the selected restaurants will serve seafood. Assume that the order of selection is not important.
at least 1= 1 or more = 1 0r 2 or 3 or 4 or 5 or 6 or 7 or 8 = 8C1+8C2+ 8C3 +8C4+8C5+8C7+8C8= 255 Answer by edjones(8007) (Show Source):
You can put this solution on YOUR website! 2C2+(2C1)(6C1)
=1+2*6
=1+12
=13 the number of ways in which you can select a restaurant for dining so that at least one of the selected restaurants will serve seafood.
