The probability of rolling a number less than 4 on a number cube is ____
1/2?
Correct.
To determine the probability of rolling a number less than 4 on a number cube, you first need to determine the total number of favorable outcomes and the total number of possible outcomes.
In the case of a standard number cube, there are six possible outcomes: 1, 2, 3, 4, 5, and 6.
Out of these six possible outcomes, the favorable outcomes (i.e., the numbers less than 4) are 1, 2, and 3.
Therefore, the probability of rolling a number less than 4 can be calculated by dividing the number of favorable outcomes by the total number of possible outcomes. In this case, it is 3 favorable outcomes divided by 6 possible outcomes.
So, the probability of rolling a number less than 4 on a number cube is 3/6, which simplifies to 1/2 or 0.5.
