one out of three adults has worked in the restaurant industry at some point during his or her life. In an office of 84 workers, how many of these people would you expect to have worked in the restaurant industry at some point?
84 * 1/3 = ?
To find how many people in the office would be expected to have worked in the restaurant industry, we need to use the given statistic that one out of three adults has worked in the industry at some point in their life.
First, we divide the total number of adults who have worked in the restaurant industry by the total number of adults:
1/3 = 0.3333...
This means that approximately 0.3333... or 33.33...% of adults have worked in the restaurant industry.
Next, we multiply this percentage by the total number of workers in the office (84) to find the expected number of people who have worked in the restaurant industry:
0.3333... * 84 = 28
Therefore, we can expect that around 28 people in the office of 84 workers would have worked in the restaurant industry at some point in their life.
To solve this problem, we can use the concept of probability. We are given that one out of three adults has worked in the restaurant industry at some point during their life.
First, we need to find the probability that a randomly chosen person has worked in the restaurant industry. Since one out of three adults has worked in the industry, the probability is 1/3.
To find the number of people in the office who have worked in the restaurant industry, we need to multiply the probability by the total number of people in the office.
Probability = 1/3
Number of people in the office = 84
Expected number of people who have worked in the restaurant industry = Probability * Number of people in the office
Expected number = (1/3) * 84
Calculating this, we find:
Expected number = 28
Therefore, we would expect around 28 out of the 84 workers in the office to have worked in the restaurant industry at some point.
