Solution

Number of boys in the class = 15Number of girls in the class = 5Total number of students in the class = 15 + 5 = 20 Number of possible outcomes = 20Since the number of boys is more than the number of girls, boys will have a higher probability. Hence, there is the higher probability of getting a copy belonging to a boy.Let A be the event of getting a boy's copy and B be the event of getting a girl's copy. PA =1520=34 And, PB =520=14
