A probability experiment consists of rolling a 6-sided die. Find the probability of the event below. rolling a number less than 4 The probability is (Type an integer or decimal rounded to three decimal places as needed.)

Step 1 ：The problem is a probability experiment that involves rolling a 6-sided die. The event we are interested in is rolling a number less than 4.

Step 2 ：The numbers less than 4 on a 6-sided die are 1, 2, and 3. So there are 3 favorable outcomes.

Step 3 ：The total number of outcomes is 6 because a die has 6 faces.

Step 4 ：The probability of an event is calculated by dividing the number of favorable outcomes by the total number of outcomes.

Step 5 ：So, the probability of rolling a number less than 4 on a 6-sided die is \(\frac{3}{6} = 0.5\).

Step 6 ：Final Answer: The probability of rolling a number less than 4 on a 6-sided die is \(\boxed{0.5}\).
