Q7 of 116 Page 42

In a school only, 3 out of 5 students can participate in a competition.

What is the probability of the students who do not make it to the competition?

Total number of students = 5

⇒ Total number of outcomes = 5


Number of students that can participate = 3


⇒ Number of students that cannot participate = 5 – 3 = 2


⇒ Total number of favourable outcomes = 2




⇒ Probability = 0.4


Hence, the probability of the students who do not make it to the competition is 0.4.
