Find the probability of not rolling a number greater than 3 on one die.
half the numbers are greater than 3
p = 1/2
To find the probability of not rolling a number greater than 3 on one die, we first need to determine the total number of outcomes and the number of favorable outcomes.
The total number of outcomes on one die is 6, as there are 6 numbers on a standard die (1, 2, 3, 4, 5, and 6).
The favorable outcomes in this case are the numbers that are not greater than 3, which are 1, 2, and 3. There are 3 favorable outcomes.
Therefore, the probability of not rolling a number greater than 3 on one die is:
Number of favorable outcomes / Total number of outcomes
P(not greater than 3) = 3/6 = 1/2 = 0.5
So, the probability is 0.5 or 50%.
