Given:

A die has 6 faces with numbers 1, 2, 3, 4, 5, and 6.

We need to find the probability of getting a number greater than 3 when rolling a die once.

Formula Used:

Probability = (Number of favorable outcomes) / (Total number of outcomes)

Calculation:

Total number of outcomes = 6 (Numbers on the die: 1, 2, 3, 4, 5, 6)

Favorable outcomes (numbers greater than 3) = {4, 5, 6}

Number of favorable outcomes = 3

Probability = Number of favorable outcomes / Total number of outcomes

⇒ Probability = 3 / 6

⇒ Probability = 1 / 2

The probability of getting a number greater than 3 is 1/2.
