Question

What is the experimental probability of selecting the name Alex?

Answer 1

The experimental probability of selecting the name "Alex" is 0.4, or 40%.

To find the experimental probability of selecting the name "Alex" from the data provided below, follow these steps:

Step 1: Count the number of times "Alex" appears.

From the data, we need to count how many times the name "Alex" is drawn.

Step 2: Count the total number of draws.

This is the total number of times a name was drawn.

Step 3: Calculate the experimental probability.

The experimental probability
`\( P \)` of an event is calculated using the formula:

`\[ P(\text{event}) = \frac{\text{Number of times the event occurs}}{\text{Total number of trials}} \]`

Apply these steps to the data provided below to calculate the experimental probability of selecting the name "Alex". Let's start by counting the occurrences of "Alex".

To calculate the experimental probability of selecting the name "Alex":

Step 1: Count the number of times "Alex" appears.

The name "Alex" appears 4 times in the draws.

Step 2: Count the total number of draws.

There are a total of 10 draws.

Step 3: Calculate the experimental probability.

Using the formula for experimental probability:

`\[ P(\text{`

`\[ P(\text{`

Therefore, The answer is 0.4 or 40%.

Answer 2

We can calculate the probability as the ratio between the positive outcomes (selecting Alex, in this case) and the total possible outcomes.

In one draw, Alex has a chance of 1 in 4, as only one of the four papers has his name on it.

The probability is 1/4 or 0.25.
