Answer 1

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 $P=\frac{F}{T}$

$P=\frac{47}{100}$    

$P=0.47$    

Therefore, The probability that a student buys a drink is 0.47.

Answer 2

The answer is 19/50 or 38%.

Hope this helps!
