A skating rink attendant monitored the number of injuries at the rink over the past year. He tracked the ages of those injured
and the kinds of skates worn during injury. The probability that an injured skater was age 12 is 0.141, the probability that an
injured skater was wearing roller skates is 0.701, and the probability that an injured skater was age 12 and was wearing roller
skates is 0.108. What is the probability that a randomly chosen injured skater was age 12 or was wearing roller skates?
