The probability that a teacher will give one surprise test during any class meeting in a week is 1/5. If a student is absent twice. What is the probability that he will miss at least one test ?

- 4/15
- 1/15
- 91/25
- 16/125
Correct Option: B
The probability of absenting of the students in the class = 2/6 = 1/3
∴ The probability of missing his test = 1/5 x 1/3 = 1/15
