Use the basic definition of probability and use a calculator to find the answers.
# of truck and motorcycle accidents 6.9 million + 171,000
P(truck or motorcycle) = ------------------------------------- = --------------------------------------
total # of accidents 15.4 million + 6.9 million + 171,000
15.4 million + 171,000
P(not truck) = P(automobile or motorcycle) = --------------------------------------
15.4 million + 6.9 million + 171,000
