Please could you help me with this. 132 people took a driving test. 80 people predicted they would pass. 64 people

didn't pass. Of these 64 people, 3 times as many people predicted they would pass
as predicated fail. Draw a frequency free to represent this information and use it to
find the probability that a person who predicted they would fail actually did. ​

You have to do 64 x 3 and that equals 192 the answer is 192 if that was what you was asking! Respond if not!
