Hi,

can nybdy give me the solution for this?

In a group of 20 office buildings, 5 have been inspected this year. Of the uninspected buildings, 3 have fire code violations. If the city randomly inspects two uninspected buildings, what is the probability that at least one of them has fire code violations?

Answer is supposed to be 13/45…

plz help…

You may want to ask this in one of the Test Prep Communities. They can better answer your question:

SAT Prep, GMAT Prep, or GRE Prep
