find the relative frequency of occurrence approach to determine the probability that a tube of toothpaste sold had packaging style 1
To determine the probability that a tube of toothpaste sold had packaging style 1 using the relative frequency of occurrence approach, follow these steps:
Step 1: Calculate the total number of tubes of toothpaste sold.
In this case, the total number of tubes of toothpaste sold is the sum of the values in both packages, which is 215 + 89 + 367 = 671.
Step 2: Calculate the number of tubes of toothpaste sold with packaging style 1.
The value for package 1 is given as 215.
Step 3: Calculate the relative frequency of occurrence of packaging style 1.
The relative frequency of occurrence is calculated by dividing the number of tubes with packaging style 1 by the total number of tubes sold. In our case, it is 215 divided by 671.
Relative frequency = Number of tubes with packaging style 1 / Total number of tubes sold
Relative frequency = 215 / 671
Step 4: Calculate the probability.
To calculate the probability, you simply take the relative frequency and express it as a decimal or a percentage.
Probability = Relative frequency
Probability = 215 / 671
So, the probability that a tube of toothpaste sold had packaging style 1 is 215 / 671, which can be expressed as a decimal or percentage.
