Answer:
The probability that a student buys a drink is 0.47.
Step-by-step explanation:
Given : At a high school movie night, the refreshment stand sells popcorn and soft drinks. Of the 100 students who came to the movie, 62 bout popcorn and 47 bought a drink. 38 students bought both popcorn and a drink.
To find : What is the probability that a student buys a drink?
Solution :
Total number of students are T=100 who came to the movie.
Student who bought popcorn = 62
Student who bought drink = 47
Students who bought both popcorn and a drink = 38
We have to find the probability that a student buys a drink.
Favorable outcome F=47
Probability is [tex]P=\frac{F}{T}[/tex]
[tex]P=\frac{47}{100}[/tex]
[tex]P=0.47[/tex]
Therefore, The probability that a student buys a drink is 0.47.
