A survey of the 1108 employees at a software company finds that 621 employees take a bus to work and 445 employees take a train to work. Some employees take both a bus and a train, and 312 employees take only a train. To the nearest percent, what is the probability that a randomly choosen employee takes a bus or a train to work? (Hint Make a Venn diagram.)

Answer:

621+445=1066
1066 people take a bus, train, or both to work.
1066/1108=.96209
about 96% of employees take a bus, train, or both to work, so the answer is 96%
