Now the maximum area of the rectangle is
= 150 - 12
= 138 ft²
L = ?

Answer:
23.72% probability that 3 of them have hardcover texts.
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
The order in which the students are chosen is not important. So we use the combinations formula to solve this question.
Combinations formula:
is the number of different combinations of x objects from a set of n elements, given by the following formula.
If you randomly choose 15 students in this class, find the probability that 3 of them have hardcover texts.
Desired outcomes:
3 with hardcover texts, from a set of 25.
15-3 = 12 with paperback texts, from a set of 75. So
Total outcomes:
15 students from a set of 100. So
Probability:
23.72% probability that 3 of them have hardcover texts.
