# 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%

**Solution:**

In a school, only 2 out of 5 students can participate in a quiz.

We have to determine the chance that a student picked at random makes it to the competition.

Total number of possible outcomes = 5

Total number of favourable outcomes = 2

The __probability__ of an event = Number of outcomes favourable to the event/Total number of outcomes in the experiment

Probability = 2/5

Percentage = 2/5 × 100

= 2 × 20

= 40%

Therefore, the required percentage is 40%
