The probability of getting at least 1 paperback when a person takes 3 books at random out of 15 books will be 0.736.
The area of mathematics known as probability studies potential outcomes of events as well as their relative probabilities and distributions. It is based on the likelihood that something will occur. The justification for probability serves as the main foundation for theoretical probability. The probability is calculated by dividing the total number of possible outcomes by the number of possible ways the event could occur.
Here,
Total selection=15C3
selection of none being paperback=10C3
Required probability=(15C3-10C3)/15C3
=(455-120)/455
required probability=0.736
When three books are chosen at random from a group of fifteen, there is a 0.736 percent chance that at least one paperback will be obtained.
