Using a standard number cube when tossed what is the probability of getting a 4 or 5
The probability of getting a 4 or 5 when rolling a standard number cube is 2/6 or 1/3. This is because there are 6 possible outcomes, which are 1, 2, 3, 4, 5, and 6. Out of these 6 outcomes, there are 2 that are either 4 or 5. So the probability of getting a 4 or 5 is 2/6 or simplified, 1/3.
Step 1: Determine the Total Number of Outcomes
A standard number cube has 6 faces numbered from 1 to 6. Therefore, there are 6 possible outcomes when rolling the number cube.
Total number of outcomes = 6
Step 2: Determine the Number of Favorable Outcomes
Since we want to find the probability of getting a 4 or 5, we need to determine how many favorable outcomes there are.
Number of favorable outcomes = 2 (either rolling a 4 or a 5)
Step 3: Calculate the Probability
The probability of an event occurring is calculated by dividing the number of favorable outcomes by the total number of outcomes.
Probability = Number of favorable outcomes / Total number of outcomes
Probability = 2 / 6
Step 4: Simplify the Probability
To simplify the probability, we divide both the numerator and denominator by their greatest common divisor, which is 2.
Probability = (2 ÷ 2) / (6 ÷ 2)
Probability = 1 / 3
Therefore, the probability of getting a 4 or 5 when tossing a standard number cube is 1/3, or approximately 0.33, which is equivalent to 33.33%.
