Final answer:
The question involves analyzing survey data on people's preferences for buying items in a shop or online and calculating the probability of randomly selecting one person who prefers to buy in a shop to win a prize.
Explanation:
The subject of the question is mathematics. It involves analyzing survey data related to the preferences of people regarding buying items in a shop or online, segmented by age groups. The question asks for the probability of randomly selecting one person who prefers to buy in a shop to win a prize.
To find the probability, we need to determine the total number of people who prefer to buy in a shop and the total number of people surveyed who prefer to buy in a shop. Then, we can use this information to calculate the probability by dividing the number of people who prefer to buy in a shop by the total number of people surveyed.
Let's calculate the probability:
- Number of people who prefer to buy in a shop = 12 (people aged 25 to 40 years) + 17 (people aged over 40 years) = 29
- Total number of people surveyed who prefer to buy in a shop = 12 (people aged 25 to 40 years) + 17 (people aged over 40 years) + 1 (randomly selected person to win a prize) = 30
- The probability of randomly selecting one person who prefers to buy in a shop to win a prize = Number of people who prefer to buy in a shop / Total number of people surveyed who prefer to buy in a shop = 29 / 30 = 0.9667 (rounded to four decimal places)
