Correct Answer - Option 2 : 2/3

**Formula used:**

Probability of an event = Number of favorable outcomes/Total outcomes

**Calculation:**

Numbers on dice not divisible by 3 are {1, 2, 4, 5}

⇒ Number of favorable outcomes = 4

Total possible outcomes = 6

**∴ The probability** **that the number shown on the dice is not divisible by 3 is 4/6 = 2/3 **
