At a recent NAU fotball game, cheerleaders were handing out of free souvenirs. They were carting around a large crate which intially contained 13 navy blue t-sherts, 27gold t-sherts,40 navy blue water bottles,30 gold water bottle, and 60 sage water bottles.

If a single item is selected from the crat at random,

What is the probability it is a water bottle?

Solution

first we count total number of items contained in Crate

=13+27+40+30+60=170

total number of water bottles= 40 navy blue water bottles+30 gold water bottle+60 sage water bottles.=130

so required probability will be 130/170 or 13/17
