Tiles with the numbers 1 through 9 are placed in a bag. What is the probability of choosing an even number that is greater than or equal to 4?
the only successes are 4,6,8
so, 3/9
Tiles with the numbers 1 through 9 are placed in a bag. What is the probability of choosing an even number that is greater than or equal to 4?
To find the probability of choosing an even number that is greater than or equal to 4, we need to determine the total number of favorable outcomes and the total number of possible outcomes.
Step 1: Count the total number of favorable outcomes.
An even number that is greater than or equal to 4 can be any of the following: 4, 6, or 8. So we have a total of 3 favorable outcomes.
Step 2: Count the total number of possible outcomes.
We have tiles numbered 1 through 9 in the bag. So the total number of possible outcomes is 9.
Step 3: Calculate the probability.
The probability is calculated by dividing the number of favorable outcomes by the number of possible outcomes.
Probability = Number of favorable outcomes / Number of possible outcomes
In this case, the probability is 3/9, which simplifies to 1/3.
Therefore, the probability of choosing an even number that is greater than or equal to 4 is 1/3.
