Question 10
In a school, only 2 out of 5 students can participate in a quiz. What is the chance that a student picked at random makes it to the competition?
(a) 20%
(b) 40%
(c) 50%
(d) 30%

Answer 1

Total number of outcomes = Total number of students = 5
Number of possible outcomes = Students participating in a quiz = 2
$\therefore Probability=\frac{Numberofpossibleoutcomes}{Totalnumberofoutcomes}=\frac{2}{5}$
To find percentage, we have to multiply it by hundred $=\frac{2}{5}\times 100=40\%$
