You roll a number cube 20 times. The number 4 is rolled 8 times.What is the experimental probability of rolling a 4?
steps on how to figure this out?
experimental probability
= (no. of successes) / (total number of trials)
=8/20
=2/5
Alright, let me explain this with a touch of humor:
Step 1: Count the number of times you rolled the number 4. You mentioned that it was rolled 8 times. Great job, by the way!
Step 2: Calculate the experimental probability. To find this, you need to divide the number of favorable outcomes (rolling a 4) by the total number of outcomes (rolling the number cube 20 times).
Step 3: So, the experimental probability of rolling a 4 would be 8 (number of times rolled a 4) divided by 20 (total number of rolls).
Step 4: Grab your calculator and divide 8 by 20. It should give you the answer, which, *drumroll*, comes out to 0.4.
Therefore, the experimental probability of rolling a 4 is 0.4, or you can simply say, "There's a 40% chance of rolling a 4 based on your 20 rolls. Don't worry, Lady Luck is on your side… mostly!"
To find the experimental probability of rolling a 4, follow these steps:
Step 1: Identify the total number of trials. In this case, you rolled the number cube 20 times. So, the total number of trials is 20.
Step 2: Count the number of times the event of interest occurred. In this case, the event of interest is rolling a 4, which occurred 8 times.
Step 3: Divide the number of times the event occurred by the total number of trials. In this case, divide 8 by 20.
Step 4: Simplify the fraction if necessary. In this case, 8 divided by 20 simplifies to 2/5.
Step 5: Convert the fraction to a percent if desired. In this case, 2/5 can be converted to 40%.
Therefore, the experimental probability of rolling a 4 is 2/5 or 40%.
To find the experimental probability of rolling a 4, you need to divide the number of times the desired outcome occurs (rolling a 4 in this case) by the total number of outcomes (rolling the number cube 20 times).
Now let's break down the steps to calculate the experimental probability of rolling a 4:
1. Count the number of times a 4 is rolled. In this case, it is given that the number 4 is rolled 8 times.
2. Determine the total number of rolls. In this case, it is given that the number cube is rolled 20 times.
3. Divide the number of times a 4 is rolled by the total number of rolls to find the experimental probability.
Experimental probability of rolling a 4 = Number of times a 4 is rolled / Total number of rolls
= 8 / 20
= 0.4 or 40%
Therefore, the experimental probability of rolling a 4 is 40% or 0.4.
