Question

A class of 25 students was asked what their favorite season was. 12 students said

Answer 1

Answer:

2 students said only fall

Step-by-step explanation:

Given:

Total number of students = 25

Number of students who like fall season (F) = 12

Number of students who like summer season (S) = 18

Number of students who like both fall and summer season $\left ( F\cap S \right )$ = 10

To find:

Number of students who like only fall season

Solution:

A set is a well defined collection of objects. A universal set is the set of which all other sets are subsets. It is denoted by U.

According to the venn diagram,

n(only F) = $=n(F)-n\left ( F\cap S \right )$

$=12-10=2$

So, 2 students said only fall.
