Answer:
[tex]Pr=\dfrac{45}{208}\approx 0.216.[/tex]
Step-by-step explanation:
You are given the information about students:
- 45 students are very short;
- 60 students are short;
- 82 students are tall;
- 21 students are very tall.
In total, there are 45 + 60 + 82 + 21 = 208 students.
Use the definition of the probability:
[tex]Pr=\dfrac{\text{Number of favorable outcomes}}{\text{Number of all possible outcomes}}[/tex]
Number of favorable outcomes = 45
Nomber of all possible outcomes = 208,
hence,
[tex]Pr=\dfrac{45}{208}\approx 0.216.[/tex]
