Number of students in senior class is 130

<em><u>Solution:</u></em>

Given that Every student in the senior class is taking history or science

85 of them taking both history and science

106 seniors takes history

109 seniors takes science

To find: number of students in senior class

Let A be the set of the students of the senior class that take history

Let B be the set of students of senior class that they science

The number of students in senior class is given by:

$|A \cup B|=|A|+|B|-|A \cap B|$

Where,

A = 106 and B = 109 and |A n B| = 85

$|A \cup B|=106+109-85=130$

Thus number of students in senior class is 130
