Single die is rolled one time, find the probability of rolling a number greater than 3 or less than 2?
4/6 = 2/3
P(1 or 4 or 5 or 6)
Either-or probabilities are found by adding the individual probabilities.
That is how Ms Sue got the answer.
Question_ a dice rolled what is the probilti that the number of dots on its upper face is 3 @ less then 3
To find the probability of rolling a number greater than 3 or less than 2 on a single die, we need to determine the total number of favorable outcomes and the total number of possible outcomes.
1. Total number of favorable outcomes:
- Greater than 3: The numbers greater than 3 on a standard die are 4, 5, and 6. So, there are 3 favorable outcomes for this condition.
- Less than 2: The numbers less than 2 on a standard die is only 1. So, there is 1 favorable outcome for this condition.
2. Total number of possible outcomes:
- A standard die has 6 faces, numbered from 1 to 6. So, there are 6 possible outcomes.
Now, we can calculate the probability using the formula:
Probability = (Number of Favorable Outcomes) / (Number of Possible Outcomes)
In this case, the probability of rolling a number greater than 3 or less than 2 is:
Probability = (Number of Favorable Outcomes) / (Number of Possible Outcomes)
Probability = (3 + 1) / 6
Probability = 4 / 6
Simplifying, we get:
Probability = 2 / 3
Therefore, the probability of rolling a number greater than 3 or less than 2 on a single die is 2/3.
