Answer:
The number of students that passed both subjects=45
Step-by-step explanation:
Step 1
Determine total number of students that passed both subjects using the expression below;
p=n-f
where;
p=number that passed both
n=total number of students
f=total number that failed both subjects
In our case;
p=unknown
n=50 students
f=5
The expression can also be written as:
number that passed both=total number of students-number that failed both subjects
replacing;
number that passed both=(50-5)=45
The number of students that passed both subjects=45
