If a bag contains 5 tiles numbered 1 to 5, what is the probability of drawing an even-numbered tile?

1. 1/5

2. 2/5

3. 3/5

4. 2/3

The correct answer is: 2/5

To determine the probability of drawing an even-numbered tile from a bag containing tiles numbered 1 to 5, we first need to identify the total number of even-numbered tiles within that set. The even numbers in the range of 1 to 5 are 2 and 4, making a total of 2 even-numbered tiles. Next, we find the total number of tiles. There are 5 tiles in total (numbered 1, 2, 3, 4, and 5). The probability of an event is calculated using the formula: \[ \text{Probability} = \frac{\text{Number of favorable outcomes}}{\text{Total number of possible outcomes}} \] In this case, the number of favorable outcomes (even-numbered tiles) is 2, and the total number of possible outcomes (total tiles) is 5. Plugging these values into the formula gives us: \[ \text{Probability} = \frac{2}{5} \] Thus, the probability of drawing an even-numbered tile is indeed 2/5. This probability indicates that if you randomly select a tile from the bag, there's a 40% chance that it will be an even-number
