The probability that ticket was a student ticket is 42 / 132
Recall :
Probability = Required outcome / Total possible outcomes
To obtain the probability that the ticket sold for space force is a student ticket :
Total possible outcomes = number of ticket sold for space force = 132 tickets
Required outcome = number of student tickets sold for space force = 42
Hence,
P(space force | student ticket) = 42 / 132
